Question

For f(x) = x + 1 and g(x) = 2x2 − x − 3, find (f − g)(x).

Answer 1

would it be d?

Answer 2

f(x) = x + 1 and g(x) = 2x2 − x − 3,
you are asked to subtract f(x) from g(x)
( x + 1)-(2x^2 − x − 3)
combine like terms the two x's are added together,
you get 2x 2x+1-2x^2+3
3 added to 1 = 4
2x+4-2x^2
move -2x^2 from left to right, in the order of polynomials
-2x^2+2x+4

Answer 3

ugh, those symbols are back again -.-
