This word describes a relation that pairs each x-value with only one y-value.
A function
200
Is this a function and why?
No, because x's repeat at 8?

600
Can a graph be nonlinear but still represent a function? Why or why not?
Yes - Think about a "V" shaped graph. This is nonlinear, but still represents a function because it passes the vertical line test (no x-values repeat).
