In below Problem, a function and its graph are given. Use the second derivative to determine intervals on which the function is concave up, to determine intervals on which it is concave down, and to locate points of inflection. Check these results against the graph shown.

1. f (x) = x3 - 6x2 +5x + 6

2. Y = x3 - 9x2

4.
y =2x4 - 6x2+4
