| | Degrees, Turnings, and "Bumps" |
 | | Because pairs of factors have this habit of disappearing from the graph (or hiding as a little bit of extra flexture or flattening), the graph may have two ;fewer, or four fewer, or six fewer, etc, bumps than you might otherwise expect, or it may have flex points instead of some of the bumps. |
 | | That is, the degree of the polynomial gives you the upper limit (the ceiling) on the number of bumps possible for the graph, and the number of bumps gives you the lower limit (the floor) on degree of the polynomial. |
 | | Quadratics are degree-two polynomials and have one bump (always); cubics are degree-three polynomials and have two bumps or none (with a flex point instead). |
