    weell that's not a quadratic equation.... you have drawn, its a cubic so degree 3

    @campbell_st So cubic are odd numbers but it is asking for the minimum wouldn't that make it 1?

    If it was a parabola I think those are even numbers

    so the minimum degree so even powers such as 2, 4, 6, 8, ... have a shape |dw:1444358275237:dw| odd powers 3, 5, 7, 9... have a shape |dw:1444358308540:dw| so your data looks like a odd degree... so 3... it your be in the form \[y = -ax^3\]
