Derivative to find maximum
WebJan 31, 2016 · One approach for finding the maximum value of y for y = a x 2 + b x + c would be to see how large y can be before the equation has no solution for x. First rearrange the equation into a standard form: a x 2 + b x + c − y = 0 Now solving for x in terms of y using the quadratic formula gives: x = − b ± b 2 − 4 a ( c − y) 2 a 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.
