    the highest order term is \(x^5\) it will effect the over all shape of the graph

    the order of \(x^5\) is 5 which is an odd number, odd ordered functions

    i'm thinking you mean local maximum and local minimum because the end behaviour of this function is they go to plus/minus infinity.

    Find f'(x). Equate it to zero. Find f''(x). Substitute the values of f'(x) in f''(x), see whether it is negative or positive. If negative, local maximum and if positive, local minimum.

    f(x)= x^5 -5x^4 +5x^3 +10 f'(x)=differentiation of f(x).

    let it be f(x) differentiate wrt x.........and equate to zero solve for x value again diferrentiate the differentiated one and substitute the x value...... if u get positve value,it has minima and vice-versa

    The function has a minimum value at x = a if f '(a) = 0 and f ''(a) = a positive number. The function has a maximum value at x = a if f '(a) = 0 and f ''(a) = a negative number.
