Question

Find ( f + g)(x).

f (x) = 3x^2 – 2
g(x) = 2x^2 – x – 2

a. ( f + g)(x) = x^4 + x
b. ( f + g)(x) = 5x^4 – x – 4
c. ( f + g)(x) = x^2 + x
d. ( f + g)(x) = 5x^2 – x – 4
e. ( f + g)(x) = –5x^2 + x + 4

Answer 1

d. (f+g)(x)=f(x)+g(x), just add the two polynomials together. you'll get 5x^2-x-4
