A qulliq is an oil lamp that functions as the main source of light and heat for an igloo in the Inuit culture. It is made of soapstone shaped as a parabolic bowl that contains seal blubber for the oil. It is lined with Arctic wool for the wick. If the length of the bowl is 30cm and the height is 9cm determine the quadratic function that can be used to model the shape of a qulliq. Express the function in vertex form.

I assume the bowl is circular, with a parabolic cross-section. If we let the vertex be at (0,0) then we have
y = kx^2
where
y(15) = 9
so,
y = 1/25 x^2
y = kx^2
where
y(15) = 9
so,
y = 1/25 x^2
