The graph of a limacon curve is given. Without using your graphing calculator, determine which equation is correct for the graph. [-5, 5] by [-5, 5]

r = 2 - 2 cos θ
r = 3 - 2 cos θ
r = 3 - cos θ
r = 3 - sin θ

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.
