In this question, we're solving the expressions.
Problem 1:
For problem 1, f(x) + g(x) means that we're combining both of the equations together by adding.
Solve:
3x + 2 + x - 3
Combine like terms:
4x + 2 - 3
Answer to problem 1: 4x - 1
Problem 2:
In this problem, you're getting both of the expressions and combining them; however, you would need to plug in -1 to the x variable in both of the expressions.
Your problem should look like this:
3(-1) + 2 - 1 - 3
Solve:
3(-1) + 2 - 1 - 3
-3 + 2 - 1 - 3
-1 - 1 - 3
-2 - 3
-5
Answer to problem 2: -5
