Find the focus, directrix, and axis of the parabola with equation:
a) x^2 = 12y
b) x^2 = 16y
It gives me a list to choose from (I can choose more than one).
Possible Answers for a:
(3,0), x = 3, x-axis
(0,3), y = -3, y-axis
(3,0), y = 3, y-axis
(0,-3), x = -3, x-axis
Possible answers for b:
(4,0), x = 4, x-axis
(0,4), y = -4, y-axis
(4,0), y = 4, y-axis
(0,-4), x = -4, x-axis
For both questions, I think the answers are options 2 and 3, but I am not sure.
