Answer 2

Range = set of possible outputs

Range = set of y values

since y values are the outputs of a function

Answer 3

so what are the y values?

Answer 4

10,8,4,4

so you list them in a set

{4, 4, 8, 10}

usually in ascending order

Answer 6

then you toss out the duplicate 4

Answer 7

so the answer is {4, 8, 10}
