Answer 1

Functions have only 1 x-value

Answer 2

They can't have 2 x-values with different y-values.

Answer 3

So that would mean this isn't a function?

Answer 4

What are the x-values here?

Answer 5

0, 1, 2, 3

Answer 6

Yes, and are any of those repeating?

Answer 7

No

Answer 8

Yes, so it's a function.

Answer 9

Now look at the y-values..are any repeating there?

Answer 10

-2, 2

Answer 11

I think my answer is, relation t is a function. The inverse of relation t is a function.

Answer 12

-2 and 2 aren't the same

And yes, that's the correct answer.

Answer 13

The y-values don't repeat, so the inverse of the function will also be a function.
