Determine the intervals on which the given function is concave up or down and find the point of inflection.

If f(x) = x(x - 5(sqrt x))


Find the x-coordinate of the point of inflection is???

For the following two questions give the largest interval in the domain of f that fits the description.

The interval on the left of the inflection point is ???. On this interval f is (concave up or down)

The interval on the right of the inflection point is ???. On this interval, f is (concave up or down.)


I'm struggling calculating the second derivative and isolating for x to find the inflection points, can someone walk me through this problem, please? Many thanks.
