Function Operations
Given the functions:
`f(x) = 4x`
`g(x) = 2x+9`
`h(x) = -4x^2-24x-27`

Determine each of the following.

Give your answers as simplified expressions written in descending order.
Find and simplify `g(x) + h(x)``g(x) + h(x) = `
 
Find and simplify `h(x) - g(x)``h(x) - g(x) =`
 
Find and simplify `f(x) * h(x)``f(x) * h(x) = `
 
Find and simplify `(h(x)) / (g(x))`, hint: you will need to factor h(x)`(h(x)) /( g(x)) = `
 
The domain restriction for `g(x) / f(x)` is `x ne`
