Question

If f(x) = 3x - 1 and g(x) = x + 2, find (1-9)(x).

Answer 1

`(f-g)(x)=2x-3`

Explanation:

The correct question is

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

we know that

(f-g)(x) is equal to subtract the function g(x) from the function f(x)

so

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

substitute the given functions

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

Remove the parenthesis

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

Combine like terms

`(f-g)(x)=2x-3`
