A function is given a Determine the net change between the g

A function is given (a) Determine the net change between the given values of the variable (b) Determine the average rate of change between the given values of the variable

Solution

f(z)= 3-4z²

f(-2)= 3- 4(-2)^2 = -13

f(0) = 3

a) Net change=f(0)-f(-2) = 3-(-13) = +16

b) Average rate of change = (f(-2)-f(0))/(-2-0) = (-16)/-2 = 8
