SOLUTION: Explain what it means for a function to be one to one. Give an example.

You can put this solution on YOUR website!
For each x value there is one y; for each y value there is one x
--------
Example: y = 3x+4 is one-to-one;its graph is a line
Example: y = x^2 is NOT one-to-one; its graph is a parabola where
certain y values are related to two different x values: (1,1) (-1,1)
