Use the graph below for this question:
graph of parabola going through negative 1, 7 and negative 3, 9.
what is the average rate of change from x = −1 to x = −3?
5
−3
1
−1

The correct option is 4. The average rate of change from x = −1 to x = −3 is -1.

Step-by-step explanation:

It is given that the graph of parabola going through (-1,7) and (-3,9).

It means the value of at x=-1 is 7.

The value of at x=-3 is 9.

The slope of a function f(x) for the interval [a,b] is

We have to find the average rate of change from x = −1 to x = −3. Here a=-1 and b=-3. So the average rate of change from x = −1 to x = −3 is

The average rate of change from x = −1 to x = −3 is -1. Therefore the correct option is 4.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
