    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 help 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. 1) 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. (Hint: Are there only x-axis intercepts? How many times can a function cross the y-axis?)
