Consider g(x) = 6 sin x + 13x on [ - TT 3T - 2' 2 Determine the intervals on which g is concave down. Og is concave down on: Og is concave down nowhere. Determine the intervals on which g is concave up. Og is concave up on: Og is concave up nowhere. Determine the value and location of any inflection point of g. Enter the solution in (x, g(x)) form. If multiple solutions exist, use a comma-separated list to enter the solutions. Og has an inflection point at: Og has no inflection point.
