What to Focus On

  • A function f(x) is increasing if f'(x) > 0.
  • A function f(x) is decreasing if f'(x) < 0.
  • The derivative represents the slope of the tangent to the curve.

  • Monotonic functions are either entirely increasing or decreasing.
  • If f'(x) ≥ 0 on an interval, f is monotonically increasing.
  • If f'(x) ≤ 0 on an interval, f is monotonically decreasing.

  • Stationary points occur where f'(x) = 0.
  • Critical points include stationary points and points where the derivative does not exist.
  • Not all stationary points are maxima or minima.

Common Mistakes to Avoid

If f'(x) = 0, then it must be a maximum or minimum point.

The second derivative test always works to determine maxima and minima.

A function is increasing if f'(x) ≥ 0, so it can be constant and still be increasing.

Memory Tips

Increasing function: f'(x) > 0

Decreasing function: f'(x) < 0

Stationary point: f'(x) = 0

Local Maximum: f'(x) changes + to -
