The table shows the outputs, y, for different inputs, x:

input (x) 2 5 9 12
output (y) 20 15 12 8

part a: do the data in this table represent a function? justify your answer.

part b: compare the data in the table with the relation f(x) = 5x + 14. which relation has a greater value when x = 9?

part c: using the relation in part b, what is the value of x if f(x) = 64?

Describe the possible echelon forms of the standard matrix for a linear transformation t where t: set of real numbers is onto.

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.
