The velocities measured at various points along the boundary layer in free convection over a vertical plate are given below (in non-dimensional form)

i	1	2	3	4	5	6
xi	0	0.2	0.4	0.6	0.8	1.0
yi	0.00	1.05	0.85	0.35	0.1	1.00

Fit a second order polynomial to the data.

I have already done all the calculations and got the formula y=-15.625x²+8.735x but I am unsure on what the graph is supposed to look like. Would just like a visual of what the graph is supposed to look like.
