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 average rate of change from x= -1 to x=-3 is -1 (Fourth option)

Step-by-step explanation:

Point A=(-1, 7)=(a, f(a))→a=-1, f(a)=7

Point B=(-3, 9)=(b, f(b))→b=-3, f(b)=9

Average rate of change from x=a to x=b:

r=(f(b)-f(a)) / (b-a)

Replacing the given values:

r=(9-7) / (-3-(-1))

r=(2) / (-3+1)

r=(2) / (-2)

r=-1
