How to use the Horizontal Line Test To Determine Whether A Function Is One To One is the topic of this video. The horizontal line test is a way of checking if our function has an inverse function. If the horizontal line test passes, we say that the function is one-to-one meaning that we can take the inverse of that function.

This video is part of our Precalculus playlist. Precalculus is typically taught in the 10th grade, however, sometime later. Precalculus courses typically cover algebra and trigonometry. The purpose of taking a Precalculus course is to prepare students with many mathematic fundamentals for future calculus courses.
