Recognizing Functions from Graphs Worksheets
Our free, printable identifying functions from graphs worksheets are a must-have to bolster skills in determining if a graph represents a function or not. Graphs show input values along the x-axis and output values on the y-axis. To figure out whether a graph represents a function or not, 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 recognizing functions from graphs worksheet pdfs are apt for grade 8 and high school kids.
