Question

If f(x) = 3x - 1 and g(x) = x + 2, find (f- g)(x). I can’t find it

Answer 1

Answer:

3x-1-(x+2)

=3x-x-2

=2x-2

Answer 2

Answer:

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

Step-by-step explanation:

We are given the two functions:

$f(x)=3x-1\text{ and } g(x)=x+2$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

By substitution:

$=(3x-1)-(x+2)$

Simplify. Distribute:

$=(3x-1)+(-x-2)$

Rearrange:

$=(3x-x)+(-1-2)$

Therefore:

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