2. Set up a number line to investigate the intervals created by the equation solutions. Pick a number in each interval and test it in the inequality. If the result is true, that interval is a solution to the inequality. There may be more than one interval which is a solution. 3. Graph the solution set.

- The key then, to finding the solution set for a polynomial inequality is to find the polynomial´s zeroes (its x-intercepts), putting them on the number line, and picking a test point in each region. Between any two consecutive zeroes, the polynomial will be either positive (if the graph is above the X-axis) or negative (if the graph is below ...
- Inclusive inequalities with the “or equal to” component are indicated with a closed dot on the number line and with a square bracket using interval notation. Strict inequalities without the “or equal to” component are indicated with an open dot on the number line and a parenthesis using interval notation.
Properties on the number line. Inequalities are governed by the following properties.All of these properties also hold if all of the non-strict inequalities (≤ and ≥) are replaced by their corresponding strict inequalities (< and >) and — in the case of applying a function — monotonic functions are limited to strictly monotonic functions.

The third grid shows the line graph without the dots because, remember, a point does not occupy any space. Hopefully, this will give you a good start in plotting points and drawing linear graphs. Obviously, you have to be good at plotting points before you can make a line graph.
- To solve your inequality using the Inequality Calculator, type in your inequality like x+7>9. The inequality solver will then show you the steps to help you learn how to solve it on your own. Less Than Or Equal To Type <= for "less than or equal to".

First we graph our boundaries; we dash the line if the values on the line are not included in the boundary. If the values are included we draw a solid line as before. Second we test a point in each region. If one point on one side of the line satisfies our inequality, the coordinates of all the points on the same side of the line will satisfy ...

Question 633934: Graph the inequality on a number line. Tell whether the graph is a segment, a ray or rays , a point or a line. 1. |X| = 0 Answer by solver91311(24404) (Show Source):
- Enter the inequality you want to plot, set the dependent variable if desired and click on the Graph button. y<x2 Systems of Equations and Inequalities In previous chapters we solved equations with one unknown or variable.
To solve a quadratic inequality we must determine which part of the graph of a quadratic function lies above or below the \(x\)-axis. An inequality can therefore be solved graphically using a graph or algebraically using a table of signs to determine where the function is positive and negative.
