1. For the equation x²+y²−2x−4y−11=0, do the following.

(a) Find the center (h,k) and radius r of the circle.

(b) Graph the circle.

(c) Find the intercepts, if any.

Expert Solution

add 1 both sides

add 4 both sides

compare with standard equation of circle

center is

radius is

.

for x-intercepts put y=0

x-intercepts are
