A student says the focus of (x - 2)
2
= 12(y + 4) is (2, 8) because 4p = 12. Which correction is best?
A
The focus is (2, -1) because p = 3 and the vertex is (2, -4).
B
The focus is (2, 12) because p = 12 and the vertex is (2, 0).
C
The focus is (5, -4) because p = 3 and the parabola opens right.
D
The focus is (-1, -4) because p = -3 and the parabola opens left.
