I have managed to get this form

**x= y[SUP]2[/SUP]/3 +1**

I have checked the graph from both forms and the vertex lies on

**(1,0)**

(as shown in this graph)

The part which I am confused at is how was the vertex was solved, I am very familiar of this form y=ax[SUP]2[/SUP]+bx+c and yet as I saw the equation I began to get confused and couldn't use the formulas used to find vertex though I tried severely here is what I got

This is my entire solution,

__since this is calculus problem though I am much concern on how to graph this new equation I just encountered, it just felt new to me i haven't encountered or recall encountering this back in analytic geometry__

**but please do ignore x=4**(i tried, im confused still)

Thank you so much and hope to get a reply soon, it will be a big help
