Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle -8 x -9 &\text{if }\displaystyle x\le0\\ \\ \displaystyle 2\cdot \sqrt{x} &\text{if }\displaystyle 0\lt x\le2\\\\\displaystyle 9-{{4}\over{6 x +4}} &\text{if } \displaystyle x\gt2 \end{cases} \]
Evaluate \(f(-5)\).
Evaluate \(f(-5)\).
