Ah, okay, so as it's explained early on is usually the vertical and horizontal line tests
a graph is a function if it passes the vertical line test, and it's a one-to-one function if it passes the horizontal line test - more formally.

Thank you ! So if the horizontal line hit the function twice is it a one to one?
