F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)

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.
