Question

How does f(x) =8(x) chAnge over the interval from x=1 to x=2

Answer 1

8

Explanation:

Given,

f(x) = 8(x)

To value of a function at any point can be calculated by substituting that value in place of x.

Therefore,

f(1) = 8(1) = 8

f(2) = 8(2) = 16

The change over the interval from x=1 to x=2 can be calculated using
`(f(2) - f(1))/(2-1)`

=>
`(16 - 8)/(1)`

=> 8
