campbell_st · Answer

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

kj4uts · Answer

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

kj4uts · Answer

If it was a parabola I think those are even numbers

campbell_st · Answer

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 

$$y = -ax^3$$
