Question

Let f(x) = 2x + 2 and g(x) = 5x2 + 2x.
After simplifying,
(f + g) (x)

Answer 1

Answer: 5x^2 + 4x + 2

Work Shown:

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

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

(f + g)(x) = (2x+2) + (5x^2+2x)

(f + g)(x) = 2x+2 + 5x^2 + 2x

(f + g)(x) = 5x^2 + (2x+2x) + 2

(f + g)(x) = 5x^2 + 4x + 2
