What is the vertical line test
👉 Learn about every thing you need to know to understand the domain and range of functions. We will look at functions represented as equations, tables, mapping, and ordered pairs. The domain is the set of all possible x or input values...

Using the vertical line test to determine if a graph is a function or not
👉 Learn how to determine whether relations such as equations, graphs, ordered pairs, mapping and tables represent a function. A function is defined as a rule which assigns an input to a unique output. Hence, one major requirement of a...

Algebra 17 - Vertical Line Test
A graph in Cartesian coordinates may represent a function or may only represent a binary relation. The "vertical line test" is a simple way to determine whether or not a graph represents a function.

How to determine if a function graph has an inverse and if the inverse is a function
👉 Learn how to find the inverse of a function. The inverse of a function is a function that reverses the "effect" of the original function. One important property of the inverse of a function is that when the inverse of a function is...

Graphing an inequality when you have to switch the sign
👉 Learn how to graph linear inequalities with one variable. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken line...
