Answer: FALSE.
Step-by-step explanation:
Given the following equation provided in the exercise:

You need to solve for the variable "x".
In order to solve for "x" you can folllow the steps shown below:
1. You must apply the Addition property of equality and add 13 to both sides of the equation. Then:

2. Finally you need to apply the Subtraction property of equality and subtract "x" from both sides of the equation. So you get:

Therefore, as you can observe, the given equation has no solutions.
In #12, substitute into the given function the x values {-3, 0, 6} to obtain the range: the function takes on the following values: {0, -1, -3}. Thus, the range for #13 is {0, -1, -3}.
Do the others in precisely the same way.
