Which of the following is true about the graph of f(x) = 2 sin³(x) + 3 sin(x) + 2 on the interval [0, π]? a) f(x) has a local minimum at the point (π,7). b) f(x) has points of inflection at the points (π/4,2√2+2) and (3π/4, 2√2+2). c) f(x) is concave down on the interval (0, π). d) f(x) is concave up on the interval (0, π). e) f(x) is increasing on the interval (π/2, π).
