Question

The vertex of this parabola is at (1,3). Which of the following could be its

equation?
(1,3) oc
O A. x=3(y - 3)2+1
O B. = 3(y - 3)2-1
O c. y = 3(x + 1)2-3
D. y = 3(x + 1)2 + 3

Answer 1

A. x = 3 (y - 3)² + 1

Explanation:

parabora open toward left or right with vertex (h,k)

x=a(y-k)²+h

h=1

k=3

x = 3 (y - 3)² + 1
