jimthompson5910 (jim_thompson5910):

Range = set of possible outputs Range = set of y values since y values are the outputs of a function

jimthompson5910 (jim_thompson5910):

so what are the y values?

OpenStudy (anonymous):

10,8,4,4

jimthompson5910 (jim_thompson5910):

so you list them in a set {4, 4, 8, 10} usually in ascending order

jimthompson5910 (jim_thompson5910):

then you toss out the duplicate 4

jimthompson5910 (jim_thompson5910):

so the answer is {4, 8, 10}
