Question

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

Answer 1

Answer:

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

Step-by-step 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

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