A. circle
B. ellipse
C. Hyperbola
D. quadratic

the equation x=-1/12y2 represents a
A. parabola
B. circle
C. hyperbola
D. ellipse

(x-3)^2+y^2=25
(x-3)^2+y^2=5^2

is
A. a circle

x=-1/12y2
x=-1/(12y^2)

is
C. hyperbola

the second is NOT at hyperbola
a hyperbola is x^2/a^2 - y^2/b^2 = 1 or y^2/a^2 - x^2/b^2 = 1

x = -1/12 y^2 is a parabola that opens to the left
