In problems 1 and 2 let f(x) = 3x +2 and g(x) = x-3

problem 1
find f(x) + g(x)

problem 2
evaluate f(-1) + g(-1)

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
