Question

F(x) =10x+5 and g(x) =3x+6 then what is (f-g) (-1)??

Answer 1

Hi

If you plug in x=-1 in the function f(x), what will you get?
and if you plug in x=-1 in the function g(x), what will you get?

Answer 2

thank you

Answer 3

-5,3

Answer 4

Right..

Now, we have to subtract the function g(x) from f(x).
(f-g) (-1) --> this is the same as : f(-1)-g(-1)

f(-1)-g(-1) = -5 -3 = ...?
