Answer:
B
Step-by-step explanation:
If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs do not classify the relationship as a function.
D is Function and A, B and C are Non-Function
If we looked at A, B and C we will see that X has the same values.
Rules: Function should always have different <em>X</em><em> </em><em>v</em><em>a</em><em>l</em><em>u</em><em>e</em><em>s</em><em>.</em>
