WebA closed (solid) dot indicates that the endpoint is included in the curve, while an open dot indicates that it is not. It’s similar to the distinction between “less than or equal to” and “less than.” Both dots in the graph you show are open, which means the function has no value and isn’t defined at x_0. WebNow an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above … circuit training for obese

WebOur final equation is f (x) {x², x<2 -1, x > 2 Notice that we use a "greater than or equal to" sign for the horizontal line's domain. The "equal to" indicates that the line y=-1 will have a closed dot at 2. But, y = x² has just a "less than" sign which indicates that the circle at 2 … Webwhen x is less than 2, it gives x 2, when x is exactly 2 it gives 6; when x is more than 2 and less than or equal to 6 it gives the line 10-x; It looks like this: (a solid dot means "including", an open dot means "not including") … WebAn open circle indictes “less than” or “greater than,” while a closed circle indicates “greater than or equal to” or “less than or equal to”.
