Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle 9 x -9 &\text{if }\displaystyle x\lt-4\\ \\ \displaystyle \sqrt{4 x +16} &\text{if }\displaystyle -4\le x\le-2\\\\\displaystyle -6 x ^2+10 x -7 &\text{if } \displaystyle x\gt-2 \end{cases} \]
Evaluate \(f(3)\).
Evaluate \(f(3)\).
