How can you tell if a graph is a function

WebExample: How about this piecewise function: It looks like this: It is defined at x=1, because h(1)=2 (no "hole") But at x=1 you can't say what the limit is, because there are two competing answers: "2" from the left, and "1" from the right; so in fact the limit does not exist at x=1 (there is a "jump") And so the function is not continuous. WebHow To: Given a graph, use the vertical line test to determine if the graph represents a function. Inspect the graph to see if any vertical line drawn would intersect the curve …
