Answer & Step-by-step explanation:
When we see (f + g)(x), it means that we are adding together f(x) and g(x).
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) = (4x + 1) + (x² - 5)
Combine like terms and make sure x² is in the front of the expression so you are following the rules of exponents when in standard form.
(f + g)(x) = x² + 4x - 4
So, (f + g)(x) equals x² + 4x - 4
