Question

can anyone remind me on how to get the domain and range from points like the one below:

{(-5,7), (0,0), (2,-8), (-7,7)}

thanks.

Answer 1

domain-
-7<x<2

range-
-8<y<7

Answer 2

how did you get the answer? is it the smallest value and greatest value of y and x?

cause -7 is the smallest for x
2 is the greatest for x
-
and -8 is the smallest for y
7 is the greatest for x

not sure about this though.
