Question

If f(x) = 3x-2 and g(x) = 2x + 1, find (f-g)(x)​

Answer 1

D.
`x-3`

Explanation:

`f(x) = 3x-2`

`g(x) = 2x + 1`

`(f-g)(x)`

`f(x)-g(x)`

`(3x-2)-(2x+1)`

`3x-2-2x-1`

`3x-2x-2-1`

`1x-3`

Answer 2

x-3

Explanation:

f(x) = 3x-2

g(x) = 2x + 1

(f-g)(x) = 3x-2 - ( 2x+1)

Distribute the minus sign

=3x-2 -2x-1

Combine like terms

= 3x-2x -2-1

=x-3​
