Consider h(y)= -1/5 y + 1/2 y^2 -3/7+7/6y^3h is concave up on:Determine the intervals on which h is concave down.h is concave down on:h is concave down nowhere.Determine the intervals on which h is concave up.h is concave up on:h is concave up nowhere.Determine the value and location of any inflection point of h. Enter the solution in (y, h(y)) form. If multiple solutions exist, use a comma-separated list to enter the solutions.h has an inflection point at:h has no inflection point.
