What does the horizontal line test tell us?

The horizontal line test is a method that can be used to determine if a function is a one-to-one function. This means that, for every y-value in the function, there is only one unique x-value.

What does the vertical line test tell us?

In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. If all vertical lines intersect a curve at most once then the curve represents a function.

What is the meaning of vertical line?

Definition of vertical line : a line perpendicular to a surface or to another line considered as a base: such as. a : a line perpendicular to the horizon. b : a line parallel to the sides of a page or sheet as distinguished from a horizontal line.

What is horizontal line?

Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.

Which is a vertical line?

What is vertical and horizontal line? A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right.

What is the vertical line?

In a coordinate plane, a line parallel to the Y-axis is called Vertical Line. It is a straight line which goes from top to bottom and bottom to top. Any point in this line will have the same value for the x-coordinate.

What does a vertical line test determine?

In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.

What does the vertical line test do?

The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines.

What does vertical line test mean?

Freebase (4.50 / 2 votes)Rate this definition: Vertical line test. In mathematics, the vertical line test is a test to determine if a curve is a relation or graph of a function when the function’s domain and range correspond to the x and y axis of the Cartesian coordinate system .

How is a vertical line test used?

The Vertical Line Test. The vertical line test is used to determine if a graph is a function. Created by: David W. Cummins. The Vertical Line Test The vertical line test is used to determine if a graph is a function. If a vertical line passes through a graph more than once, the graph is not the graph of a function.
