Question

Given:
f(x) = -4x + 2
g(x) = 2x^2 + 4x - 5

Find:(f + g)(x)

Answer 1

2x ^ 2 - 3

Explanation:

f(x) = -4x + 2

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

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

= 2x ^ 2 - 4x + 4x + 2 - 5

= 2x ^ 2 - 3

Answer 2

2x^2-3

Explanation:

f(x) = -4x + 2

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

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

Combine like terms

= 2x^2-4x+4x+2-5

=2x^2-3
