ANSWER


y ={x}^(2) + 2

Step-by-step explanation

The equation of a parabola that has vertex at (h,k) is given by:


y = a {(x - h)}^(2) + k

If the given parabola has vertex at (0,2), then h=0 and k=2.

Considering the possible answers, we must have a=1.

We substitute the values in to the formula to get:


y =1 {(x - 0)}^(2) + 2


y ={x }^(2) + 2

The first option is correct.
