Ray and kelsey have summer internships at an engineering firm. as part of their internship, they get to assist in the planning of a brand new roller coaster. for this assignment, you ray and kelsey as they tackle the math behind some simple curves in the coaster's track.

part a

the first part of ray and kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.

ray and kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. ray says the third-degree polynomial has 4 intercepts. kelsey argues the function can have as many as 3 zeros only. is there a way for the both of them to be correct? explain your answer.
