4. Quadratic The u shape is called a parabola.

5. Cubic That graph is odd because it has rotational symmetry around the origin.

6. Absolute Value It makes a V for Absolute V alue.

7. Radical (square root) The domain has to start at zero because you can’t take the square root of a negative.

8. Inverse/Rational The graph has a bottom & top, just like the equation.
