The vertical line test is when you put vertical lines down the graph and if the point does not touch the line more than once, it passes and represents a function.
Answer: -16
Step-by-step explanation:
-3 is less than -2 so use the first one
Plug into equation
5(-3)-1
-15-1= -16
You may notice that all of the terms have a common factor: 
. So, let's take the out of all the terms. This gives us:
Using the Zero Product Property, we can say that both 
and 
.
Let's solve both. is obvious, but we still need to solve our other term:
- Apply the Zero Product Property
Our answer is x = -6, 0, 4.
A(6) and D(-4) are solutions to the equations
(6)^2 < 81 | 36 < 81
(-4)^2 < 81 | 16 < 81
