I need help!! Given a quadratic function, which choice explains the meaning of the zeros graphically?

a) f(x)= (x+p) (x+q) where p and a correspond to the x-intercepts

b) f(x)= (x-p) (x-q) where p and a correspond to the x-intercepts

c) f(x)= (x-p) (x-q) where p and a correspond to the vertex

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.
