Consider the following function:y=f(x)=((x-1)^3)(x-5)
1)find dy/dx.
2)solve dy/dx=0 for x.
3) find the critical values of x and hence critical points.
4)find the intervals where the graph of y=f(x) is increasing or decreasing.
5)find d^2/dx2
6)from the expression of d^2/dx2, find whether the graph of the function is concave upward or concave downward at the critical points.
7)for what values of x, the function attains relative maxima and relative minima.
8)find the relative maxima and relative minima values of the function.
9)find the point of inflection if any.
