Answer 1

Think about it. It's a function if there are no two y-values for any given x-value. Moving along the graph, you see that every x-value has one y-value. Would it be a function?

Answer 2

true?

Answer 3

Does it pass the vertical line test? Does any vertical line cross the curve at most one time?

Answer 4

nope

Answer 5

Right, so it'd be a function.

Answer 6

Any vertical line crosses the curve at most once,
so it does pass the vertical line test,
it is a function.
