Consider the function f(x)=x^3-1. Which of the following functions is f^-1(x)?

Answer:

First number = 5, second number = 3

Step-by-step explanation:

we can write this as x–5y = –10 and x – 2y = –1 so we know now that 3y = 9 so we divide both by 3 to get: y = 3

now that we know the second number we can multiply it by 2 to get 6 and now we just have to figure out what – 6 is –1 which would be 5

The decreased numbers are first number is 2. and the second number is -9.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

Given that, there are two numbers, first of two numbers decreased by five times the second number equals -10. The first number decreased by two times the second number equals -1.

x - y = 0

The first number decreased 5 times

-5 -y = -10

-y = -10 + 5

-y = -5

y = 5

The second number decreased 2 times

x - (-2) = -1

x + 2 = -1

x = -1 -2

x = -3

Now,

the first number is

-3 - 5 = -10

-8 = -10

10-8 = 0

2 = 0

the second number is

-3 - 5 =-1

-8 = -1

-8 +1 =0

-9 = 0

Hence, the answer is 2, -9.

One example of a function that is its own inverse is the square root function. The square root function takes a number and returns its inverse, which is always negative.

For example, the square root of 4 is equal to -2, and the square root of -3 is equal to 3. This means that you can multiply a number by -1 and then take the square root to get the same number as the original number. This proves that the inverse of a number is always a negative number. The opposite of a square is known as a rectangle. This shows that the square functions as its inverse. Another example of a function that is its own inverse is the exponential function. The exponential function takes two numbers and returns the reciprocal of their product. This means that the exponential function is also its own inverse because the reciprocal of a product is equal to the product of the reciprocals.

The probability that both people have their ears pierced is calculated by dividing the number of people with pierced ears by the total number of people in the sample. This can be expressed as a fraction, with 430/2000 = 0.215, or 21.5%.

Probability is a measure of how likely an event is to occur. It is stated as a number between 0 and 1, with 0 indicating that the occurrence is impossible and 1 indicating that the event is unavoidable.

In this question, by dividing the number of persons with pierced ears by the total number of participants in the sample to find the chance that both people have their ears pierced. In this situation, the answer is 430/2000 = 0.215.

This may be read as follows: 430 persons out of every 2000 get their ears pierced. Therefore the chance of picking two persons at random from this sample who both had their ears pierced is 0.215, or 21.5%.

This may also be stated as a fraction, with the numerator being the number of persons with pierced ears (430) and the denominator representing the total number of participants in the sample (2000). As a result, the likelihood is 430/2000, or 0.215.

The exact area of the circle is 4π [tex]units^2[/tex].

The center of the circle is at the origin (0,0)

The diameter of the circle = 4 units.

So, the radius of the circle = 2 units.

The circle passes through points (2,0) and (-2,0). The given points are on the x-axis and they are exactly 2 units away from the origin

The area of a circle  A = π [tex]r^2[/tex],

where A is the area, π is approximately 3.14 and r is the radius of the circle.

As we know according to the distance formula the distance between points (x₁, y₁) and (x₂, y₂) is given by,

[tex]d = \sqrt{[(x_2 - x_1)^2 + (y_2 - y_1)^2]}[/tex]

Here we have been given points (2, 0) and (-3, 2)

Let us assume that  (x₁, y₁) = (2, 0)

The answer for the Daffynition Decoder is 7.

The formula is O3 - M2 = 7. The calculation is to take the ozone (O3) and subtract the mistletoe (M2). O3 stands for ozone, which is composed of three atoms of oxygen and is represented by the number 3. M2 stands for mistletoe, which is composed of two atoms of oxygen and is represented by the number 2. The formula used to calculate the answer is m = 2o + 1, where m is the number of mistletoes and o is the number of ozones. The calculation is as follows: if there are 2 ozones, then the number of mistletoes is 2(2) + 1 = 5. Therefore, the answer is 7 (5 mistletoes and 2 ozones). This formula is useful for quickly calculating the total number of items when you know the number of each type of item.Therefore, if we subtract the mistletoe from the ozone, we get the answer of 7.

The linear equation that gives the rule for this table is y = 19x - 12.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The standard linear equation can be represented as:

y = mx + b

where, m is the slope and b is the y-intercept of the line.

From the table we can see the two points through which the point passes is:

(x1, y1) = (2, 26)

(x2, y2) = (3, 45)

The slope of the line is given by:

m = (y2 - y1) / (x2 - x1)

m = (45 - 26) / (3 - 2)

m = 19 / 1 = 19

The slope m = 19.

The point-slope form of the line can be written as:

y - y1 = m (x - x1)

y - 26 = 19 (x - 2)

y - 26 = 19x - 38

y = 19x - 38 + 26

y = 19x - 12

Hence, the linear equation that gives the rule for this table is y = 19x - 12.

The equation y = -2 is represented on the graph as shown below :

Use the slope-intercept form to find the slope and y-intercept.

The slope, m, represents the steepness of a line. The slope of the line is also termed as gradient, sometimes. The y-intercept, b, of a line, represents the y-coordinate of the point where the graph of the line intersects the y-axis.

The slope-intercept form is

y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Find the values of m and b, using the slope-intercept equation.

y = -2

m = 0, b = -2.

The slope of this line = m = 0

The y-intercept = -2, therefore a point on the line = (0,-2)

Finding two points on the line:

(0,-2), (1,-2)

Thus, the equation y = -2 on graph is shown below.
