Question

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

Answer 1

`\large \boxed{(f - g)(x) = f(x) - g(x)}`

We subtract the f(x) by g(x) which means that we subtract 3x-1 from x+2.

`\large{(f - g)(x) = (3x - 1) - (x + 2)}`

Cancel the parentheses by distributing the negative sign in x+2.

`\large{(f - g)(x) = 3x - 1 - x - 2}`

Combine like terms.

`\large{(f - g)(x) = 2x - 3}`

Answer

• (f-g)(x) = 2x - 3
