Question

There are eight steps to the problem. First find then determine the domain for each function.

Answer 1

Given the functions:

`\begin{gathered} f(x)=3x^2-9x+6 \\ g(x)=x-1 \end{gathered}`

The sum of the functions is;

`\begin{gathered} (f+g)(x)=3x^2-9x+x+6-1 \\ (f+g)(x)=3x^2-8x+5 \end{gathered}`

The domain of a function is a set of values for which the function is real and defined.

The domain of a quadratic function is always;
