for the graphed exponential equation, calculate the average rate of change from x=-2 to x= 0

Answer:
3/2
Step-by-step explanation:
Rate of change is given by
f(x2) -f(x1)
-----------------
x2 -x1
We know x2 is 0 and x1 is -2
f(x2) is -1 and f(x1) is -4
-1 - ( -4)
----------
0 - -2
-1 +4
--------
0+2
3/2
