1.) Find (f - g)(x) if f(x) = 2x - 5 and g(x) = 4.

Question

2.) Given f(x) = 4 and g(x) = 2x - 1, find (f - g)(x).

Thanks so much! :)

Answer 1

if f(x) = 2x-5 and g(x) = 4
then
(f-g)(x) = 2x-5 - 4 = 2x - 9

Do #2 in the same way

Answer 2

@ Reiny,

Would #2 be -2x - 3?

Answer 3

How did you get -3 ?

(f-g)(x)
= 4 - (2x-1)
= 4 - 2x + 1
= -2x + 5
