y = -x^2+2

Step-by-step explanation:

The equation for a parabola is

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

where (h,k) is the vertex

The vertex of our parabola is (0,2)

y = a(x-0)^2 +2

y =ax^2+2

We need one more point to determine a

(2,-2)

-2 = a(2)^2 +2

-2 = 4a+2

Subtract 2 from each side

-2-2 =4a

-4 =4a

Divide by 4

-4/4 =4a/4

-1 =a

y=-1 x^2+2

y = -x^2+2

t hope this
