Inequalities

Use > or < for dashed boundaries, and <= or >= for solid ones.

Learning Opportunity

The shaded area represents the Solution Set the infinite number of points $(x, y)$ that satisfy the inequality. When you graph two inequalities, the double-shaded area is the solution to the system.

Solid line = Boundary Included

Dashed line = Boundary Excluded

How Inequality Graphing Works

Inequality graphing visualizes the set of all coordinate points (x, y) that make the inequality true. The "solution set" is represented as a shaded region on the graph.

1
Dashed lines: Boundary not included (< or >)
2
Solid lines: Boundary included (<= or >=)
3
Shading above: y > f(x)
4
Shading below: y < f(x)

Goal

y < f(x), y > f(x), etc.

Graph inequalities to find the solution regions and their intersections.

Example

Equation: y > x^2 This shades the region above the parabola x-squared. Use <= or >= for solid boundary lines, and < or > for dashed lines.

Frequently Asked Questions

How do I graph y > x^2?

Simply type "y > x^2" into the input box. The region above the curve will be shaded automatically.

What is the difference between solid and dashed lines?

Dashed lines represent a strict inequality (< or >), while solid lines are used for "less than or equal to" (<=) or "greater than or equal to" (>=).

Can I graph multiple inequalities?

Yes! You can enter multiple inequalities to see overlapping solution regions.
