Answer:
The average rate of change from x=-7 to x=-5 is -3
Step-by-step explanation:
In order to calculate average rate of change we would have to make the following calculation:
According to the given data we have the following:
x=-7 so, f(-7) is to be calculated in the graph y
x=-5 so, f(-5) is to be calculated in the graph y
Therefore, average rate of change=f(-5)-f(-7)/-5-(-7)
average rate of change=3-9/2
average rate of change=-6/2
average rate of change=-3
The average rate of change from x=-7 to x=-5 is -3
