Answer:
y=-(x-2)^2+2
Step-by-step explanation:
The equation for a parabola is y= a(x-h)^2+k.
The turning point is (2,2) which represents the (h,k) value
y=a(x-2)^2+2
Now solve for a. by using the y-int is (0,-2), and plugging it into the equation.
-2=a(0-2)^2+2
a= -1
Plug your a value into the equation.
y=-(x-2)^2+2
