WebDec 20, 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.
