SOLVEDUse a graphing calculator in function mode to graph each circle

To graph a circle, start by finding the center, which is represented as "a" and "b" in the equation for the circle. Then, plot the center of the circle on that point on the graph. For example, if a = 1 and b = 2, you'd plot the center at point (1, 2). Next, find the radius of the circle by taking the square root of "r" in the equation.. In order to graph a circle, the function for a circle would need to be solved for Y. To graph the unit circle (x 2 +y 2 =1), first, solve for y, and then input the results into the Y= Editor. If the graph looks like an oval, use the Zoom Square feature followed by Zoom In or Zoom Out to change the viewing window.

Toggle the graphs on below to see what I mean. How does it work? It's a differently-shaped parabola, with absolute value so it can appear to be a circle You need to keep the absolute value sign, or else it will look like something different, sort of like a basketball pattern.. a. As a team, translate the graph below horizontally and vertically. Then write an equation in graphing form for this family of circles using h and k. Be prepared to share your results and your strategies with the class.
