Determine the intervals on which the graph of y = f(x) is concave up or concave down, and find the x-values at which the points of inflection occur. f(x) = x(x – 5v). x > 0 (Enter an exact answer. Use symbolic notațion and fractions where needed. Give your answer in the form of a comma separated list, if necessary. Enter DNE if there are no points of inflection.)

Question
Determine the intervals on which the graph of y = f(x) is concave up or concave down, and find the x-values at which the points of inflection occur. f(x) = x(x – 5/x), x > (0 (Enter an exact answer. Use symbolic notațion and fractions where needed. Give your answer in the form of a comma separated list, if necessary. Enter DNE if there are no points of inflection.) Incorrect (Use symbolic notation and fractions where needed. Give your answers as intervals in the form (*, *). Use the symbol ∞ for infinity, U for combining intervals, and an appropriate type of parenthesis "(". "D", "I", or "J", depending on whether the interval is open or closed. Enter Ø if the interval is empty.)
