fail vertical line test

• a method to determine if a graph is a function or not

• vertical line drawn ANYWHERE through a graph DOES intersect the graph in more than one location

• y variables in a function

• An equation that describes the relationship between input and output.

pass vertical line test

• A relationship that assigns exactly one output (range) value to one input (domain) value.

• the output value of a function

• y variables in a function

• vertical line drawn ANYWHERE through a graph does NOT intersect the graph in more than one location

how to - vertical line test

• draw a vertical line ANYWHERE through a graph and see if it intersects at more than one location

• vertical line drawn ANYWHERE through a graph does NOT intersect the graph in more than one location

• if a graph is function, a vertical line (up and down) drawn through it should only cross that graph at ___________ point(s)

• the input value of a function
