Question

Help me pleaseeeee i needd help!

Answer 1

`(3)/(2)`

Explanation:

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

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

Here [ a, b [ = [ 2, 6 ]

From the table

f(b) = f(6) = 19 and f(a) = f(2) = 13, thus

average rate of change =
`(19-13)/(6-2)` =
`(6)/(4)` =
`(3)/(2)`
