How do you shade inequalities?

Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line. For a vertical line, larger solutions are to the right and smaller solutions are to the left.

How do you shade on a graphing calculator?

Press [ALPHA][Y=] or [ALPHA][WINDOW] to display the Shades menu. Because the Shades option at the bottom of the graph screen is above the F1 and F2 function keys on the calculator, pressing either [ALPHA][Y=] to select F1 or [ALPHA][WINDOW] to select F2 produces the Shades menu, as illustrated in the first screen.

How do you shade in math?

There are three steps:

  1. Rearrange the equation so “y” is on the left and everything else on the right.
  2. Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
  3. Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).

How do you decide where to shade an inequality whose boundary does not go through the origin?

Check to see if this point satisfies the inequality. If it satisfies the inequality, shade the region which contains that point. If it does not satisfy the inequality, shade the region which does not contain that point.

How to Shade Graph Unions and Intersections on Your TI-84 Plus

  1. Press [ALPHA][Y=] or [ALPHA][WINDOW] to display the Shades menu.

How to add Colored shading to a Desmos graph?

With inequalities, you can add colored shading to your Desmos graph. Use strict inequalities ( < and > < a n d > ) for dotted lines and non-strict inequalities ( ≤ and ≥ ≤ a n d ≥ ) for a solid line.

How do you shade a graph of an equation?

First, graph the “equals” line, then shade in the correct area. There are three steps: Rearrange the equation so “y” is on the left and everything else on the right.

How do I make a table in the DESMOS calculator?

To make a table in the Desmos graphing calculator simply type table, or use the Add Item menu (plus sign in the top left of the expression list) and scroll down to Table. For each instance above, click the gear icon at the top of the expression list ( Edit List) and then click the table icon next to the expression ( Convert to Table ).

How do you restrict the domain of a graph in Desmos?

How do you restrict a domain on Desmos? To limit the domain or range (x or y values of a graph), you can add the restriction to the end of your equation in curly brackets {}. For example, y=2x {1<3} would graph the line y=2x for x values between 1 and 3. You can also use restrictions on the range of a function and any defined parameter.
