Question

If f(x)=x/4 -3 and g(x) = 4x^2 + 2x -4 find (f+g) (x)
the answers are
4x^2 + 7/4x -7
4x^2 + 9/4x + 1
4x^2 + 9/4x -7
x^2 -12

Answer 1

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

so you have

\[(f + g)(x) = 4x^2 + 2x + \frac{x}{4} -4 - 3\]

just collect the like terms... to simplify

Answer 2

^ I agree with @campbell_st
