Question

Given the function with f(3) = 127 and f(1) = 95, determine the rate of change over the interval 1 <3 <3

32
16
32
O 16

Answer 1

When we have a function f(x) = y.

The rate of change between a and b (where a < b) is:

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

In this case:

b = 3

a = 1

f(3) = 127

f(1) = 95

R = (127 - 95)/(3 - 1) = 16

The rate of change in that interval is 16.
