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
