Sign charts are used to analyze functions or solve inequalities. Learn what a sign chart is, how they work and how you can draw a sign chart.

A sign diagram shows the SIGN of the OUTPUT-values of a function for each input value in the domain. Let's start with a polynomial that's already factored. The term (x-a) is the line y = x a, …

Sign diagrams are used to work out the SIGN (+ or -) of the y values in between each x intercept. You only need to choose ONE value in between each x intercept, because they will all be the...

Below is the sign diagram for three linear expressions, denoted as , and (colour coded), where are constant whose value you can change by operating with your mouse on the sliders.

Overview. The word "sign" in sign diagram refers to the y value on a graph. There are only 4 possible signs that y value can take on:

Graphs of functions can be time consuming to create, especially if we only wish to know when the function is positive, negative, zero or undefined. A sign diagram is a time-efficient way to do this.
