These unique features make Virtual Nerd a viable alternative to private tutoring. Using vertical line test, the graph given represents a function as the vertical line drawn intersects the graph at only one point. Horizontal Line Test vs. Vertical. Fortunately, there is an easier way. Virtual Nerd's patent-pending tutorial system provides in-context information, hints, and links to supporting tutorials, synchronized with videos, each 3 to 7 minutes long. Solved Examples. Examples of Vertical Line Test. For example, on the interval [–π/2, π/2], y = sin x is one-to-one and therefore has an inverse for that interval. Watch this tutorial and learn about the vertical line test. A graph will be considered as a function if it has only one output y for each input x. The equation of a vertical line does not have a y-intercept since a vertical line never crosses the y-axis. A vertical line is drawn across the edge of the ruler from one end of the x-axis to the other end. Answer: D 2. The vertical line test tells you if you have a function, while the horizontal line test tells you if that function is one to one (injective). The Vertical Line Test. The vertical line test is a simple method for determining if an equation is indeed a function. Working With Graphs. ; Vertical lines help determine if a relation is a function in math. The test states that a graph represents a function if and only if all vertical lines intersect the graph at most once. This is also called a vertical line test. ()The slope of a vertical line is undefined because the denominator of the slope (the change in X) is zero. More About Vertical Line Test.
