Question: Graph the equation after determining the x- and y-intercepts and whether the graph possesses any of the three types of symmetry. 9. y = 4

Graph the equation after determining the x- and y-intercepts and whether the graph possesses any of the three types of symmetry.

9. y = 4 - x2

12. x = y2 - 1

15. y = -1 / x3

42. Specify the center and radius of each circle. Also, determine whether the given point lies on the circle.

(x + 4) 2 + (y + 2)2 = 20; (0, 1)

45. Determine the center and the radius fo r the circle. Also, find the y-coordinates o f the points (if any) where the circle intersects the y-axis.

x2 + y2 =5
