If f(x)=x/4-3 and g(x)=4x^2+2x-4 find (f+g)(x) can someone do this step by step? .

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

Yeah she/ he needs look how long that is man
