Určte prvú deriváciu funkcie \(f\colon y = \root{5}\of{x^{2} - 7x}\). Poznámka: Funkcia \(f\colon y = \root{5}\of{x}\)
je definovaná pre \(x\in \left < 0;\infty \right )\).
\(f^{\prime}(x) = \frac{2x-7}
{5(x^{2}-7x)^{\frac{4}
{5} }} ;\ x\in \left (-\infty ;0\right )\cup \left (7;\infty \right )\)
\(f^{\prime}(x) = \frac{2x-7}
{5(x^{2}-7x)^{\frac{4}
{5} }} ;\ x\in \left (-\infty ;0\right \rangle \cup \left \langle 7;\infty \right )\)
\(f^{\prime}(x) = (2x - 7)\root{4}\of{x^{2} - 7x};\ x\in \left (-\infty ;0\right )\cup \left (7;\infty \right )\)
\(f^{\prime}(x) = (2x - 7)\root{4}\of{x^{2} - 7x};\ x\in \left (-\infty ;0\right \rangle \cup \left \langle 7;\infty \right )\)
