Question

What is the vertex of `y= 4(x-2)^2-12`?

Answer 1

`"vertex "=(2,-12)`

Explanation:

`"the equation of a parabola in "color(blue)"vertex form"` is.

`color(red)(bar(ul(|color(white)(2/2)color(black)(y=a(x-h)^2+k)color(white)(2/2)|)))`

`"where "(h,k)" are the coordinates of the vertex and a"`
`"is a multiplier"`

`y=4(x-2)^2-12" is in vertex form"`

`"with "h=2" and "k=-12`

`rArrcolor(magenta)"vertex "=(2,-12)`
