Which table represents a relation that is not a function

A table of values is not going to be a function if two y values have the same x value.

If you run a vertical line through the x and get 2 y values, you are not dealing with a function. The one that does that is D. You have 3 and the two y values for x = 3. Those two y values are -4 and 0.

p> q if you calculate p is100 q is 79

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
