To determine if a function is increasing or decreasing, take the derivative and evaluate it at the x-value in question. If the derivative is positive, that means the slope is positive (because derivative is the slope), and therefore the function is increasing. If the derivative is negative, then the slope is negative and …

Witryna20 gru 2024 · This leads us to a method for finding when functions are increasing and decreasing. THeorem 3.3.1: Test For Increasing/Decreasing Functions. Let f be a continuous function on [a, b] and differentiable on (a, b). If f ′ (c) > 0 for all c in (a, b), then f is increasing on [a, b].

Witryna20 gru 2024 · The key to studying f ′ is to consider its derivative, namely f ″, which is the second derivative of f. When f ″ > 0, f ′ is increasing. When f ″ < 0, f ′ is decreasing. f ′ has relative maxima and minima where f ″ = 0 or is undefined. This section explores how knowing information about f ″ gives information about f.
