Open Circle Math Graph
You count out 4 in every direction from the center.
Open circle math graph. In this case you get r 4. On a graph all those points on the circle can be determined and plotted using x y. Hence the domain in interval notation is written as 8 4 4 2 2 2. Graph x 2.
It means that the solution can be any number on the right of 2. An open circle is used if the value at the end point is excluded from the feasible region while a closed circle is used if. Is the distance from that center point to the circle itself. Realize that the circle is centered at the origin no h and v and place this point there.
Notice that 2 is not shaded because 2 is not included in your solution. Draw a non shaded or open circle at 2 and shade everything on the right of 2. Calculate the radius by solving for r. Set r squared 16.
Plot the radius points on the coordinate plane. An open or closed circle are used to graph an inequality in one variable. The shaded area in red is your solution. The coordinates of the center point and the radius of a circle.
The graph starts at values of x 8 and ends at values of x 2.
