WebHow to do the Horizontal Line Test. Step 1: Draw a horizontal line through the graph of the function. Step 2: Determine how many places the line intersects the graph. WebMay 27, 2024 · To test if a function is one-to-one, we can apply the horizontal line test. As soon as you graph the graph of a function, draw horizontal lines over the graph. If a horizontal line passes through the graph of the function at more than one spot, then the function is not one-to-one.
