    You should know from your text that:

    a. f(x) increasing is where f'(x) > 0, and decreasing is where f'(x) < 0.
    b. local max is where f'(x) = 0 and f''(x) <0; local min is where f'(x) = 0 and f''(x) >0.
    c. Concave up is where f''(x) >0. Concave down is where f''(x) <0.
    d. Inflection points are where f''(x) = 0.
