Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle x-9 &\text{if }\displaystyle x\lt2\\ \\ \displaystyle {{1}\over{4 x -7}}-1 &\text{if }\displaystyle 2\le x\lt5\\\\\displaystyle \sqrt{x-2} &\text{if } \displaystyle x\ge5 \end{cases} \]
Evaluate \(f(-2)\).
Evaluate \(f(-2)\).
