Which equation represents a graph with a vertex at (1, - 6) ?

A. y = 3x2 + 6x - 3

B. y = 3x2 - 6x - 3

C. y = 3x2 - 8x - 1

D. y = 3x2 - 3x - 6

For the answer to the question above asking Which equation represents a graph with a vertex at (1, - 6) ?

The answer is the second one among the given choices which is B. y = 3x2 - 6x - 3

For the explanation,

write y+6=3 (x^2-1) ^2=>

y+6=3x^2-6x+3=>

y=3x^2-6x-3
