How we can determine from the graph of a function if the function is a one-to-one function? Describe how to use the graph of a one-to-one function to draw the graph of its inverse function. What is a circle? Does (x−3)2 +(y−5)2 =0 represent the equation of a circle? If not, describe the graph of this equation. Does (x−3)2 +(y−5)2 = −25 represent the equation of a circle? What you can say about the graph of this equation?
