Question

If given f(x) = x + 4 and g(x) = –2x2 + 3x – 1, what is (f – g)(x)?
A.
(f – g)(x) = –2x2 + 4x – 3
B.
(f – g)(x) = –2x2 – 2x + 5
C.
(f – g)(x) = 2x2 + 2x + 5
D.
(f – g)(x) = 2x2 – 2x + 5
Please Help

Answer 1

(f – g)(x) = f(x) - g(x)

Answer 2

ok so that would be\[(x+4)-(2x ^{2}+3x-1)\]

Answer 3

-2x^2

Answer 4

ok so \[(f-g)(x)=2x ^{2}-2x+5?\]

Answer 5

yes.
