17. the graph of a limacon curve is given. without using your graphing calculator, determine which equation is correct for the graph.
a circular graph with an indentation on the left toward the origin, but not touching the origin
[-5, 5] by [-5, 5]
a) r = 2 + 3 cos θ
b) r = 3 + 2 cos θ
c) r = 2 + 2 cos θ
d) r = 4 + cos θ
18. determine if the graph is symmetric about the x-axis, the y-axis, or the origin.
r = 4 - 4 cos θ

19. a railroad tunnel is shaped like a semiellipse, as shown below.
a semiellipse is shown on the coordinate plane with vertices on the x axis and one point of intersection with the positive y axis.
the height of the tunnel at the center is 58 ft, and the vertical clearance must be 29 ft at a point 21 ft from the center. find an equation for the ellipse.
20. determine if the graph is symmetric about the x-axis, the y-axis, or the origin.
r = 4 cos 5θ
