Graphing polynomials -
i have to design a roller coaster with at least four equations of polynomials. i have the first equation as y = 4x3 + 9x2 + 2x + 5 but i'm not sure how to add more to make it look like a roller coaster. i only have down two equations and it looks like this:

can anyone me figure out how to make the lines in the graph to look like a roller coaster?

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
