Hi. I need this checked please.

Domain [ 0, +Infinity)
Range (-infinity, +infinity)
The relation is not a function.........................................[edited]

Since I can’t edit the post I’m going to change what I said about the relation being a function here.

The relation is not a function. It does not pass the vertical line test. Any one element of the domain should correspond to only one element of the range for it to be a function.

Since it’s possible to draw a vertical line that will cut the function more than once it can’t be a function.

Hi, your answer looks fine, besides the small typo. Indeed it is not a function.
