In your lab, a substance's temperature has been observed to follow the function t(x) = (x + 5) + 9. the turning point of the graph is where the substance
changes from a solid to a liquid. using complete sentences in your written answer, explain to your fellow scientists how to find the turning point of this function.
hint: the turning point of the graph is similar to the vertex of a quadratic function.

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.
