Question:

For the given functions {eq}f {/eq} and {eq}g {/eq}, algebraically find {eq}(f - g) (x) {/eq}.

{eq}\displaystyle f (x) = -5 x^3 - 7 x^2 - 8 x,\ g (x) = 12 x^3 - 6 x + 1 {/eq}

Function Operations:

Functions may be combined or subtracted from each other. The difference between two functions may be found by subtracted one function from the other given that the two functions have overlapping domains.
