| Given the functions: f(x)=9x g(x)=2x+1 h(x)=8x2-2x-3 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≠ |
