Question

What is the vertex of `y= -2(x+1)^2 +7`?

Answer 1

`"vertex "=(-1,7)`

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+1)^2+7" is in vertex form"`

`"with "h=-1" and "k=7`

`color(magenta)"vertex "=(-1,7)`
