Let's examine the two relations below this These two relations differ by only 1 number! (look carefully, this graph is slightly different from the prior problem's graph). At any particular input value, there can be only one output if the relation is to be a function. However, I really struggled to find ANY resources to teach it. Problems 14a - 14b: Use the vertical line test to identify graphs in which y is a function of x. If we think of a vertical line as an infinite set of x-values, then intersecting the graph of a relation at exactly one point by a vertical line implies that a single x-value is only paired to a unique value of y.
