If S1 ands2 are respectively the sets of local minimum and local maximum points of the function fX9x
Hi Sasidhar,
If you could submit the whole equation then I can help you better with the solution. Until then, I am writing the solution of a similar question through which you can get help in your questions of similar types.
Let the function be f(x)
f(x) = 9x^4 + 12x^3 - 36x^2 + 25
f(x) = 36x^3 + 36x^2 - 72
f(x) = 36x ( x^2 + x - 2)
f(x) = 36x (x+2) (x-1)
Minima = -2 , Maxima = 0 , Minima = 1
S1 = -2 ,1
S2 = 0
