Differentiate the following function. \[ f(x) = \root{5}\of{x^{2} - 7x} \]Remark: The function \(f\colon y = \root{5}\of{x}\) is defined for \(x\in \left < 0;\infty \right )\).
\(f^{\prime}(x) = \frac{2x-7} {5(x^{2}-7x)^{\frac{4} {5} }} ;\ x\in \left (-\infty ;0\right )\cup \left (7;\infty \right )\)
\(f^{\prime}(x) = \frac{2x-7} {5(x^{2}-7x)^{\frac{4} {5} }} ;\ x\in \left (-\infty ;0\right ] \cup \left [ 7;\infty \right )\)
\(f^{\prime}(x) = (2x - 7)\root{4}\of{x^{2} - 7x};\ x\in \left (-\infty ;0\right )\cup \left (7;\infty \right )\)
\(f^{\prime}(x) = (2x - 7)\root{4}\of{x^{2} - 7x};\ x\in \left (-\infty ;0\right ] \cup \left [ 7;\infty \right )\)
