Use the graph of the function shown below to find:
A. The value of y when x is equal to each of the following: -3, -2, 0, 2, 4.
B. The value of x when y is equal to each of the following: -1.5, 0, 2, 2.5.
C. The domain of the function.
D. The range of the function.
Part A: 0, 2.4, 2.4, 1, 2
Find the y coordinate of the point on the graph with the given x coordinate.Part B: -2.5, 6, 0.5, N/A
Find the x coordinate of the point on the graph with the given y coordinate.
Part C: [-3, 7]
The domain is the set of x values.Part D: [-1, 2.4]
The range is the set of y values.A. The value of y, when x is equal to -3, -2, 0, 2, 4, is 0, 2.4, 2.4, 1, 2 respectively.
B. The value of x, when y is equal to -1.5, 0, 2, is -2.4, -3, and 4 respectively.
C. The domain of the function is {-3, -2, 0, 2, 4}.
D. The range of the function is {0, 1, 2.4}.
A. To find the value of y at x is equal to -3, -2, 0, 2, 4 is found by the graph given.
x: -3 -2 0 2 4
y: 0 2.4 2.4 1 2
B. To find the value of x at y is equal to -1.5, 0, 2, is found by the graph given.
y: -1.5 0 2
x: -2.4 -3 4
C. The domain of a function is the set of all possible input values (in this case, x values) for which the function is defined.
From the given x values, we can see that the function is defined for all of these values: -3, -2, 0, 2, 4.
So, the domain of the function is {-3, -2, 0, 2, 4}.
D. The range of the function:
The range of a function is the set of all possible output values (in this case, y values) that the function can produce.
From the given y values, we can see that the function produces these y values: 0, 1, 2.4.
So, the range of the function is {0, 1, 2.4}.

The triangle below is reflected about the y-axis and then translated 4 units to the left.
The resulting triangle isA A'B'C' . What is the measure of angle C'?
1. 35°
2. 55°
3. 63°
4. 125°
Answer:
55⁰
Step-by-step explanation:
a + b + c = 180⁰
35⁰ + 90⁰ + c⁰ = 180⁰
125⁰ + c⁰ = 180⁰
180⁰ - 125⁰ = 55⁰
c = 55⁰

During the last three seconds of the objects's time in the air, it is

The average rate of change of h over the interval is -48 feet per second.
Given,
The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by
h(t) = −16t2 + 96t, 0 ≤ t ≤ 6.
We need to find the average rate of change of h over the interval [3, 6].
How do we find the average rate of change of a function over an interval?If we have an interval [a, b] and a function f(x).
The rate of change is given by:
= f(b) - f(a) / b - a
We have,
h(t) = −16t² + 96t and [3, 6].
h(6) = -16 x 6² + 96 x 6 = -576 + 576 = 0
h(3) = -16 x 3² + 96 x 3 = -144 + 288 = 144
The average rate of change of h is:
= h(6) - h(3) / 6 - 3
= 0 - 144 / 3
= -144 / 3
= -48
Thus the average rate of change of h over the interval is -48 feet per second.

Dave and his brother, Theo, are selling cookies by the pound at the school bake sale. Dave sold 14.84 pounds of cookies and Theo sold 21.45 pounds of cookies. How many pounds did they sell altogether?
Can someone tell me the answer pls
Step-by-step explanation:
a normal function expresses y (the functional result) in terms of x (and constants).
we need to transform this to express now x in terms of y (and constants).
at the end we only rename x into y and y into x to make it an actual function.
h(x) = y = (-5x + 6)/(3x + 4)
y(3x + 4) = (-5x + 6)
3xy + 4y = -5x + 6
4y - 6 = -5x - 3xy = x(-5 - 3y)
x = (4y - 6)/(-5 - 3y)
and after renaming we get therefore the function
y = h-1(x) = (4x - 6)/(-3x - 5)
