Question

does this set of ordered pairs represent a function?why or why not? (-5,-5),(-1,-2),(0,-2),(3,7),(8,9)

Answer 1

yes, because the x-axis are all different

Answer 2

Yes it does! look at the x-values (the first numbers) each x-value is only listed once. This means that it is a function because a function can only show each x-value once. For example 3 couldn't have been used twice. Hope this helps
