Answer:
A function can only be called a function if each x-value has only one y-value. If the x-value has two y-values, but the y-values are the same, that's an exception. If the x-value has two y-values that are different, it is not considered a function.
Step-by-step explanation:
If you are looking for me to explain how a graph is a function, let me know.
X and Y values create functions and they help you to solve equations. Functions are used in all types of math including geometry and algebra.
Hope this was simple enough to understand! Have a nice day
