Which set of ordered pairs represents y as a function of x ? F {(0,0), (-1,2), (-1,-2), (-2,4), (-2,-4)}
G {(0,0), (1,1), (2,4), (3,9), (3,16)}
H {(0,0), (0,1),(0,2), (0,-1), (0, -2)}
J {(0,0), (-1,-0.5), (-2,-1), (-3,-1.5), (-4,-2)}

Your answer is J. To determine this, you can graph this and do the Vertical line test. This is the easiest method to use! When u draw a straight line on the graph and if it hits the line more than once, it is NOT a function of x. Nope this helps!!

Igotchu on that if you still need it

I’m pretty sure the answer is counter steer.
