Question

F(x) = 4x2 + 5x – 2

g(x) = 5x – 2x2 – 3x + 4

Which function represents the sum of the functions, h(x) = f(x) + g(x)?

h(x) = 5x + 2x2 + 2x + 2
h(x) = –x2 + 2x + 2
h(x) = 5x – 4x2 + 4x + 2
h(x) = 5x + 2x2 – 2x – 2

Answer 1

Therefore, the function that represents the sum of f(x) and g(x) is h(x) = -2x^2 + 9x + 2.

Explanation:

h(x) = f(x) + g(x) = (4x^2 + 5x - 2) + (5x - 2x^2 - 3x + 4)

h(x) = -2x^2 + 9x + 2

Therefore, the function that represents the sum of f(x) and g(x) is h(x) = -2x^2 + 9x + 2.

Answer 2

the answer is A. h(x) = 5x + 2x2 + 2x + 2
