Answer:
It is not a Function!
Step-by-step explanation:
The easiest way to tell if a graphed line is a function is the Vertical Line Test. If you draw a vertical line across the original line given and it only crosses through a curve once, then it is a function. If it crosses it more than once, it is not a function.
If you drew a line through this graph, it would touch more than one curve at a time, confirming it as a non- function.
Regards!
