Answer:
G(x)=x³-1
because it intersect at the negative side of y
Answer:
g(x) = x³ - 1
(option C)
Step-by-step explanation:
We know that the shape of the graph has not changed, as stated in the question, meaning that the change has not happened as a direct change to x (like 2x³ instead of x³).
The entire graph has been moved down and not left/right, which would have happened inside the parenthesis (like g(x) = (x³ - 3)).
Because it has been shifted down (as evident by the y-intercept), and we know that the shape has not changed, we know that the original function was shifted down 1 --which can be expressed by the equation g(x) = x³-1

What is an inverse function?An inverse function is a function that reverses the action of another function, such that the inverse function maps the output of the function to the corresponding input.
The inverse of the function can be found by graphing the function, f(x) = x³ + 3·x + 1, using technology and then using inverse or table function to find the values of the inverse functions at the specified points
a. The value of the inverse function, f⁻¹(1), is the x-value, on the graph that corresponds to the point with a y-coordinate of 1.
The graph of the function indicates that at a y-value of 1, x = 0, therefore;
f⁻¹(1) = 0
b. Similarly, the graph indicates that a y-value of 5, x = 1, therefore;
f⁻¹(5) = 1
c. When the y-value = 3, we get;
x³ + 3·x + 1 = 3
x³ + 3·x - 2 = 0
Solving the above equation with an online tool, we get; x ≈ 0.59607
Therefore; f⁻¹(3) ≈ 0.59607

Explanation:
In matrix A, the upper left corner is -3
Multiply this with -7 to get -7*(-3) = 21
So we'll have 21 in the upper left corner of matrix -7A. The other entries will be handled in a similar fashion.
Meanwhile, the upper left corner of matrix B is 9. Multiply this with -4 to get 9(-4) = -36 which is the upper left corner entry of matrix -4B
Combine those products: 21 + (-36) = -15
The number -15 is the upper left corner entry in matrix -7A-4B
This points us to choice A as the final answer.

Answers
Answer:
Using the formula multiplicity, we find that the equation of the function will be [tex]f(x)=-(x+6)^{3} (x-2)^{4}[/tex]. The graph is in the attachment.
Step-by-step explanation:
Concept: Given that for -6, multiplicity is 3 and for 2 multiplicity is 4.
So, the equation of multiplicity is represented as:
[tex]f(x)=a(x-root)^{mutliplicity}[/tex]
This gives the following function
[tex]f(x)=a(x+6)^{3} (x-2)^{4}[/tex]
The equation has a negative leading coefficient.
This means that, the value of a is less than 0 i.e. a < 0
Assume any value of a (say a = -1), the equation becomes

A graph displays point A (5, 3, 4) and point B (−4, 2, 6). Calculate the approximate distance each point is from the origin. Round to the nearest tenth. Which point is farther from the origin, and by how much?
Answers
Distance from the origin to the points ≈ 0.41.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²]
Point A (5, 3, 4) and point B (−4, 2, 6) are located away from the origin (0,0,0), and the points from the origin to this points are expressed as OB - OA where;
Let OB is the distance from the origin to the point B
Let OA is the distance from the origin to the point A
Using the formula for calculating the distance between two points;
OA = √(z2-z1)²+(y2-y1)²+(x2-x1)²
OA = √(4-0)²+(3-0)²+(5-0)²
OA = √(16)+(9)+(25)
OA = √50
OA = 7.071
Similarly;
OB = √(6-0)²+(2-0)²+(-4-0)²
OB = √(6)²+(2)²+(-4)²
OB = √36+4+16
OB = √56
OB = 7.4833
Distance from the origin to the points = 7.4833 - 7.071= 0.4123
Distance from the origin to the points ≈ 0.41
