A. X = 3(y + 3)2 + 5
B. x = 3(y - 5)2 - 3
C. X= -3(y + 3)2 + 5
D. y = -3(x - 5)2-3

Answer 1

The vertex of a parabola is written as (h,k) so h = 5 and k = -3.

H is subtracted from x inside parentheses and k is added at the end of the equation.

The equation is also written as y =

The answer should be D.

Answer c also works, so there are two correct answers.

Answer 2

Answer:

C

Step-by-step explanation:

X= -3(y + 3)2 + 5 is the answer
