Question

Given f(x)=2x^2+3x and g(x)=5x^2−2x−6 . What is (f+g)(x) ? 10x^2+x+6 7x^2+x−6 ​ −3x^2+5x+6 ​ ​ 3x^2−5x−6 ​

Answer 1

7x^2+x−6

Explanation:

(f+g)(x) will be obtained by adding the the functions f(x) and g(x);

f(x)=2x^2+3x

g(x)=5x^2−2x−6

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

= 2x^2+3x + 5x^2−2x−6

= 7x^2 +x -6
