Which equation represents a graph with a vertex at (1, -6)?
y=3x² + 6x - 3
y=3x² - 6x - 3
y=3x² – 8x-1
y=3x² – 3x-6

B.

Step-by-step explanation:

Well, we can use the following formula to find the x coordianate of the vertex  -b / 2a.

So let’s start with a)

-6 / 6

-1

A. is wrong because its vertex starts with -1.

b)

6 / 6

1

now that we have our x coordinate we can plug it into the equation to get our y.

3 - 6 - 3

So the y coordinate is -6.

Hence, the answer choice B.
