Answer:
Step-by-step explanation:
Do you have the options?
For the vertical line test, you can only use the X once per Y. You can not have more than one X.
The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.
So when you look at f(-2), find the Y value where the line crosses.
At X-2, the line crosses Y at -2
At X = 2, the line crosses at Y = 2
At X = 4, the line crosses at Y = 1
The answer is -2,2,1
