Question:

For the given functions {eq}f {/eq} and {eq}g {/eq}, find the requested function.

{eq}f(x) = x - 4; g(x) = 4x^2 {/eq}

Find {eq}(f + g)(x) {/eq}.

Adding Two Functions:

The addition of two functions is found by simply adding the definitions of the functions if they have the same independent variables. Suppose {eq}f(x) {/eq} and {eq}g(x) {/eq} are two functions; the addition of two function is expressed as {eq}(f+g)(x). {/eq}
