- When a first derivative is positive, the original function is increasing.
- When a first derivative is negative, the original function is decreasing.
- The derivative does not tell us if the function is positive or negative, only if increasing or decreasing.
- When a second derivative is positive, the original function is concave up.
- When a second derivative is negative, the original function is concave down.
- When a first derivative hits zero from below the axis, the original function is at a(n) local minimum.
- When a second derivative is zero, the original function is at a(n) inflection point.
