Which of the following could be the equation for a parabola that opens down with vertex (-11, -28)?
A. x=-5(y + 28)2 - 11
B. y= -5(x +11)2 - 28
C. X= 5(y +11)2 - 28
D. y = 5(x+28)2 - 11

B.

Step-by-step explanation:

the negative 5 means that the parabola will open down. the positive 11 in the parentheses is graphed as a negative 11 and the negative 28 stays the same.
