What are the values of the variables in the triangle below?

step-by-step explanation:

the first one and the second one that's the answer

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
