a. Y = 3X^2

Parabola (opens upward)

Vertex (0, 0)

Min value = 0

Focus (0, 1/12)

Directrex: y = -1/12

Length of latus rectum = 1/3

Axis of symmetry: x = 0

X-intercept=0

b. (X-1)^2 + (Y-8)^2 = 16

Circle

Center (1, 8)

Radius = 4

c. (X+2)^2 + (Y-4)^2 = 36

Circle

Center(-2, 4)

Radius=6

d. Y = X^2 - X

Parabola

See if you can figure the rest of this one.
