Question

Determine the average rate of change from 0 to 3.

Answer 1

It is A, there you go!

Answer 2

A

Explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

`(f(b)-f(a))/(b-a)`

Here [ a, b ] = [ 0, 3 ]

From the graph

f(b) = f(3) = 4

f(a) = f(0) = - 3 , thus

average rate of change =
`(4-(-3))/(3-0)` =
`(7)/(3)` → A
