You can put this solution on YOUR website!
let's see
when x=1 or x=2 then y=0
when x=0 or x=3 then y=2
when x=4........then y=6

A good way to start is a scatter plot to see how the data points are distributed.
.

.
That looks like a parabola, so you're trying to fit a set of points to a quadratic equation.
.
y = x^2
.
But we can see the graph needs to be shifted to the right by about 3/2 and it needs to drop by about -1/3.
.
So it looks like:
.
y = (x-3/2)^2 - 1/3
.
Graphing we find.

Looks like a pretty good fit to me...

Done.
