Question

f(x) = 2x - 1 + 3 and g(x) = 5x - 9, what is (f - g)(x)?

Answer 1

This can also be expressed as (2x - 1 + 3)-(5x-9)

Answer 2

Group your like terms like this:
\[(2x - 5x) + (-1 + 3 - 9)\]

Answer 3

Then do you combine the like terms?

Answer 4

Yup!

Answer 5

Ok but then answers look like this (f-g)(x)=2^x-1-5x....

Answer 6

Are you sure you gave me the correct question?

Answer 7

Positive

Answer 8

I don't think so, it is most likely (2x^2 - 1x + 3) - (5x-9)

Answer 9

Okays
