Christi is doing her math homework. to receive full credit, she must answer this question: what key features are necessary—and how are the features used—to create the sketch of a polynomial function? what is christi's correct answer, so she receives full credit for the question? explain in complete sentences.

Christi should know the "zeros" of the polynomial function for sketching the graph of it (where the graph intersects with the x an y-axises, if it does). Also, she needs to know the vertical and horizontal stretches/shrinks for that. Finally, she should know the basic function of the polynomial function such as x^2, 1/x and etc.

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
