Write a quadratic function in vertex form with a vertex at (-4,2)

y = ( x + 4 ) ^ 2 + 2

Step-by-step explanation:

vertex form of quadradtic is:

y = a ( x − h ) ^ 2 + k

with vertex (-4,2) = (h,k)

y = a ( x − (-4) ) ^ 2 + 2

y = a ( x + 4 ) ^ 2 + 2

'a' can be any non-zero real value

say a = 1
