what is the possible way to find that the stationery point of the cubic curve lies on x axis?Equation of the curve is given.

Bimal....it is just like as you did with quadratic curve
1) find dy/dx
2) put dy/dx=0 and you'll get 2 values for x
3) then put these values (one by one) and find the corresponding value for y
4) you now have two stationary points

thats not gud enough to get full marks......
after putting values of x in the given equation of y if u get the value y=0 then it is likely to say that ur stationary pts. lie on the x-axis!!!!!

so do as u like NIKESH

You can also factorize the cubic function into one linear and one quadratic function and then solve for the roots

By the way next time kindly post your question with more information such as the function.
