Question

Perform the requested operation or operations. f(x) = 7x + 6, g(x) = 4x2 find (f + g)(x).

Answer 1

The answer is A (7x+6+4x^2)

The other answer is right but it isn't in the order given.

Answer 2

(f + g)(x) = 7x + 6 + 4x² = 4x² + 7x + 6

The notation given means to add the rules of f(x) and g(x), and since there are no like terms, your answer is 4x² + 7x + 6
