Answer:
2x-3
Step-by-step explanation:
f (x) = 3x - 1
g(x) = x + 2
(f - g)(x) = 3x-1 - ( x+2)
Distribute the minus sign
= 3x-1 -x-2
Combine like terms
= 3x-x-1-2
= 2x-3
Answer:
(f - g )( x ) = 2 x - 3
step-by-step explanation:
f ( x ) = 3x - 1
g ( x ) = x + 2
- (f - g )(x ) = ( 3x - 1 ) - ( x + 2. )
remove unnecessary parantheses
- 3 x - 1 - x - 2
collect like terms
- 3x - x - 1 -2
- 2 x -3
