Use your grapher to determine which of the graphs matches the polar equation r = 1 + 2 cos θ. a circular graph with an inner loop on the left a circle tangent to the y-axis, symmetric about the axis, and lying in quadrants one and four a circular graph with an indentation on the left to the origin a graph of four loops originating at the origin lying on and symmetric about the and y-axes This is not multiple choice so please explain your answer... I need help FAST but I need reliable answers pleaseee! :)
