Question

Please help me!!!!!!!!!!!

What is the vertex of the parabola?

y+4=12(x−7)2

Enter your answer in the boxes.
(___,___)

Answer 1

I just took the quiz and got (7,-4) 

Answer 2

The given parabola is
`y+4=12(x-7)^2`. Compare with the standard equation of a parabola in vertex form,
`y-c=a(x-b)^2`.

The vertex of this parabola is
`(b,c)`. Compare
`y+4=12(x-7)^2` with the standard equation
`y-c=a(x-b)^2`.

we see
`c=-4,b=7`. Thus, the vertex of the given parabola is
`(7,-4)`.
