F (x) = x-7

g (x) = 4x^3

What is f (x) + g (x) ?

f (x) + g (x) = x+x

f (x) + g (x) = 4x^3+x-7

f (x) + g (x) = -4x^3-x+7

f (x) + g (x) = 4x^3+x

    f (x) + g (x) = 4x^3+x-7

    Step-by-step explanation:

    To find f (x) + g (x) add the expressions together by combining like terms. Recall like terms are terms with the same base and exponent.

    f (x) + g (x) = x - 7 + 4x^3

    f (x) + g (x) = 4x^3 + x - 7
