Question

Please help.

Let f(x) = 4x - 5 and g(x) = 6x - 3. Find f(x) - g(x).

A. -2x - 2
B. -2x - 8
C. 2x + 5
D. 2x - 5

Answer 1

4x - 5 - (6x - 3) =
4x - 5 - 6x + 3 =
-2x - 2 <==

Answer 2

`f(x)-g(x)=-2x-2`

Explanation:

we are given

`f(x)=4x-5`

`g(x)=6x-3`

now, we can find f(x)-g(x)

`f(x)-g(x)=4x-5-(6x-3)`

we can simplify it

`f(x)-g(x)=4x-5-6x+3`

`f(x)-g(x)=4x-6x+3-5`

now, we can combine like terms

`f(x)-g(x)=-2x-2`
