Question

Please help! What is the range of y = 5x -2 if the domain is {-3, -1, 0, 1, 3}?
a {-13, -3, 2, 3, 1}
b {12, 3, 0, 3, 13}
c {-17, -7, -2, 3, 13}

Answer 1

Domain = x values
range = y
values
substitute x for each domain value to get the range

Answer 2

so i'd start with y=5(-3)-2 right?

Answer 3

good!

Answer 4

So y would equal -17

Answer 5

correct now substitute x for the next number in domain
just like u did for -3

Answer 6

(-17)=5(-3)-2
(-7)=5(-1)-2
(-2)=5(0)-2
(3)=5(1)-2
(13)=5(3)-2
So the answer is { -17, -7, -2, 3, 13}

Answer 7

yes correct! good job!

Answer 8

Thank you!

Answer 9

my pleasure!
