If f(x) = -3 3 and g(x)= 4x2 + 2x - 4, find (f +g)(x).
​

You are really just adding the two functions together to create a new function.

x/4 -3+4x^2+2x-4  (making everything have a common denominator of 4 we get:

(x-12+16x^2+8x-16)/4  combine like terms in numerator

(16x^2+9x+4)/4

A. 4x² + 9x/4 - 7

Step-by-step explanation:

Step 1: Define

Identify

f(x) = x/4 - 3

g(x) = 4x² + 2x - 4

(f + g)(x) is f(x) + g(x)

Step 2: Find
