Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle \sqrt{-x-5} &\text{if }\displaystyle x\lt-5\\ \\ \displaystyle 2 x ^2-8 x -9 &\text{if }\displaystyle -5\le x\lt1\\\\\displaystyle {{7}\over{4 x +22}}-9 &\text{if } \displaystyle x\ge1 \end{cases} \]
Evaluate \(f(-3)\).
Evaluate \(f(-3)\).
