Answer:
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.
