Differentiate the equation and let dy/dx = 0 to find the stationary points. Determine whether it's min or max point then from there you can sketch the curve

Done. I have used the second derivative test instead of the first derivative test for the nature of the stationary points (max, min or inflection) as the expression for dy/dx is quite simple.

What u mean by first or second
There are two different ways of checking the nature of the stationary points. One method is the first derivative test, which looks at the values of dy/dx around a stationary point. The other method is the second derivative test, which tells us directly the nature given the signage of d2y/dx2.
Let me know if you need me to write down both methods.
Sorry I still don’t get it on this
Ok wait, I will need some time to write down the explanations.
Ok.
Did u saw my qns on 3b that I comment it

Wait let me see, I will after that write down the workings for this question
Ok
I could not find it. At a much later time I switch on my phone and see if I can find it.
Ok thank you
You can read up on my notes first
can
Can u find the qns ?
Done
You can post the next one once ready
Tomorrow I will post, too many right now
Thank you
Thank you
I will be available tmr from 11:30 pm onwards; I can do bit by bit while I am outside from 7 pm onwards.
