Question

The following graph of f(x)=x2 has been shifted into the form f(x)=(x-h)2+k

Answer 1

K is the y coordinate of the vertex   which is -2.

Answer 2

k is equal to
`-2`

Explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

`f(x)=a(x-h)^(2)+k`

where

(h,k) is the vertex of the parabola

In this problem the vertex of the parabola is the point
`(4,-2)`

therefore

h is equal to
`4`

k is equal to
`-2`
