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

Question

amistre64 · Answer

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

amistre64 · Answer

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

WAIT. i get it. you have to graph the function table, then draw a line through it, and if it goes through more than one, its not a function?
