Graphs are visual tools that show input values along the x-axis and output values on the y-axis making it easier to comprehend relationships. To figure out whether a graph represents a function or not, instruct high school students to apply the vertical line test. Try drawing a vertical line, if it intersects the graph more than once suggesting that it has more than one output value, then be assured it does not represent a function as a function has only one output value for each input value. These printable identifying functions from graphs worksheets are a must-have for your students to bolster skills in determining if a graph represents a function or not.

These pdf worksheets are apt for grade 8 and high school students.
