Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle \sqrt{3-x} &\text{if }\displaystyle x\lt3\\ \\ \displaystyle -{{10}\over{x}}-7 &\text{if }\displaystyle 3\le x\le9\\\\\displaystyle x^2+7 x +4 &\text{if } \displaystyle x\gt9 \end{cases} \]
Evaluate \(f(5)\).
Evaluate \(f(5)\).
