Question

What is the vertex of `y=2(x-2)^2-9`?

Answer 1

`(2,-9)`

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=2(x-2)^2-9" is in vertex form"`

`rArrcolor(magenta)"vertex "=(2,-9)`
