1. Complete the square in order to put the equation into standard form. Identify the center and the radius or explain why the equation does not represent a circle.

Solution:

Center: (0, 2)

Radius = √9 = 3

Thus, this is a equation of a circle with center (0, 2) and radius 3.

2. Find the standard equation of the circle with endpoints of a diameter

and .

Solution:

Center of the circle =

Diameter

Radius = diameter = /2 =

Equation of the circle will be

3. Find an equation of a parabola satisfying ...
