Function concave up and down calculator.

When f''(x) is positive, f(x) is concave up When f''(x) is negative, f(x) is concave down When f''(x) is zero, that indicates a possible inflection point (use 2nd derivative test) Finally, since f''(x) is just the derivative of f'(x), when f'(x) increases, the slopes are increasing, so f''(x) is positive (and vice versa) Hope this helps!
