Which of the following equations best describes the curve shown in the graph?

1. y² = x
2. y = x
3. y = x²
4. y² = x²
5. 2y = x

It’s a good idea to know what the graphs of common equations such as y = x² look like, but if you forget or would like to double-check your answer, you can plug the x and y values of a few points on the graph into the given equations to see which one works. Be careful of using points like (0, 0), as they may work for several of the answer choices.
