Answer:
Step-by-step explanation:
Given (x - 2)^2 + (y + 3)^2 = 9, compare this to the standard equation of a circle, (x - h)^2 + (y - k)^2 = r^2.
It then becomes obvious that h = 2 and k = -3; the coordinates of the center of the circle are (2, -3).
If r^2 = 9, then r must be 3. This is the radius of the circle.
To draw this circle: Plot the center (2, -3). Take a compass and open it up so that the distance between the compass points is 3, representing the radius of the circle. Now use the compass to draw a circle with radius 3 and center at (2, -3).
Domain is all the x's
and range is all the y's
so domain is {1, 2, 3, 4}
and range is {2, 7, 12, 17}
