Q:

Select all the correct locations on the table.The table below contains points on an exponential function, f. Select the two points in the table which create an interval with an average rate of change of -60.

Accepted Solution

A:
Average rate of change: r=[f(b)-f(a)]/(b-a)

r=-60→[f(b)-f(a)]/(b-a)=-60

b=5; f(b)=-213; a=1; f(a)=27
(-213-27)/(5-1)=(-240)/4=-60

Answer: The two points in the table which create an interval with an average rate of change of -60 are:
x     f(x)
1      27
5   -213
