Question

Find the average rate of change of a function that contains the points (-2.3) and (2,5).

Answer 1

-
`(1)/(2)`

Explanation:

The average rate of change of a function in the closed interval [ a, b ] is

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

Here [a, b ] = [ - 2, 2 ]

with f(b) = 3 and f(a) = 5, thus

average rate of change =
`(3-5)/(2+2 )` =
`(-2)/(4)` = -
`(1)/(2)`
