Question

Which set of ordered pairs represents a function

{(0,1),(1,2),(2,3),(3,3)}
{(0,1(,(1,2),(1,3),(2,5)}
{(0,0),(1,2),(2,4),(2,6)}
{(0,0),(0,1),(2,0),2,4)}

Answer 1

(0,1) (1,2) (2,3) (3,3)

Explanation: A function must past the vertical line test. For this to be true, each input (x-value) must only have one output (y-value). Since the first answer meets this criteria, while all the others have two outputs for each input, this would be the correct answer.

I hope this helps!
