Answer 1

Refer to explanation

Explanation:

Using function notation the average rate of a function `f(x)` from a to x is

`Δ(x)=(f(x)-f(a))/(x-a)`

where

`Δ` is the name of this average rate of change function

`x-a` represents the change in the input of the function f(x)

`f(x) - f(a)` represents the change in the function of f(x) as the input changes from a to x
