a. for which value of does = 1 have only one solution?
b. for which value of does = 1 have only ±1 as solutions?
c. for which value of does = 1 have only ±1 and ±ii as solutions?
d. for which values of does = 1 have ±1 as solutions?

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.

Will mark brainliest! ( explain the answer too, it can be one sentence)

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
