Question #bd799

Answer 1

`f(a+h) = 3(a+h)^2 + 2` or `f(a + h) = 3a^2 + 6ah + 3h^2 + 2`

Explanation:

To solve this problem you need to substitute `(a + h)` into the equation for everywhere in the equation there is an `x` or:

`f(a+h) = 3(a+h)^2 + 2`

If you want to expand this would equal:

`f(a + h) = 3(a + h)(a + h) + 2`

`f(a + h) = 3(a^2 + 2ah + h^2) +2`

`f(a + h) = 3a^2 + 6ah + 3h^2 + 2`
