Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle \sqrt{-2 x -8} &\text{if }\displaystyle x\le-4\\ \\ \displaystyle 3 x ^2-8 x -7 &\text{if }\displaystyle -4\lt x\lt2\\\\\displaystyle x-5 &\text{if } \displaystyle x\ge2 \end{cases} \]
Evaluate \(f(-3)\).
Evaluate \(f(-3)\).
