Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle \sqrt{16-4 x } &\text{if }\displaystyle x\lt4\\ \\ \displaystyle x-9 &\text{if }\displaystyle 4\le x\le7\\\\\displaystyle {{1}\over{x-3}}-10 &\text{if } \displaystyle x\gt7 \end{cases} \]
Evaluate \(f(-5)\).
Evaluate \(f(-5)\).
