A polynomial function has degree 7. What is the largest number of turning points it can have?

1. A turning point is where the graph changes from rising to falling or from falling to rising. 2. The largest number of turning points is always one less than the degree. 3. With degree 7 that gives 7 minus 1, which is 6. 4. Reading the degree itself as the answer would give 7, which is the ceiling on x-intercepts instead. _Source: OpenStax Precalculus (CC BY 4.0), section 3.4 Graphs of Polynomial Functions_
