Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle \sqrt{-2 x -8} &\text{if }\displaystyle x\lt-4\\ \\ \displaystyle 9 x -7 &\text{if }\displaystyle -4\le x\lt-2\\\\\displaystyle 1-{{152}\over{8 x +36}} &\text{if } \displaystyle x\ge-2 \end{cases} \]
Evaluate \(f(5)\).
Evaluate \(f(5)\).
