Answer 1

I... don't understand why the answer below had such low ratings??!

The answer 1/2 is correct on khan academy if Im looking that the right question..

Explanation:

Answer 2

`(1)/(2)`

Explanation:

Given the function
`h(x)=(1)/(8)x^3-x^2`

The average rate of change of the function h(x) over the interval
`a\le x\le b` can be calculated using formula

`(h(b)-h(a))/(b-a)`

In your case,

`a=-2,\\ \\b=2,`

so the average rate of change is

`(h(2)-h(-2))/(2-(-2))\\ \\=(((1)/(8)\cdot 2^3-2^2)-((1)/(8)\cdot (-2)^3-(-2)^2))/(4)\\ \\=((1-4)-(-1-4))/(4)\\ \\=(-3+5)/(4)\\ \\=(2)/(4)\\ \\=(1)/(2)`
