Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle {{11}\over{2 x -3}}-9 &\text{if }\displaystyle x\lt0\\ \\ \displaystyle -x^2+9 x -9 &\text{if }\displaystyle 0\le x\lt7\\\\\displaystyle \sqrt{3}\cdot \sqrt{x} &\text{if } \displaystyle x\ge7 \end{cases} \]
Evaluate \(f(-4)\).
Evaluate \(f(-4)\).
