Question

how do u use a verticle-line test to determine weather a graph is a graph of a function?

Answer 1

you draw lines that are pretty much straight up and done the graph; if they hit in more than one spot; its not a function

Answer 2

a function is defined as one y for every x; so if a vertical line hits 2 ys; it fails tha function definition
