Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle x^2+x-4 &\text{if }\displaystyle x\lt-4\\ \\ \displaystyle \sqrt{3 x +12} &\text{if }\displaystyle -4\le x\le0\\\\\displaystyle 7 x -4 &\text{if } \displaystyle x\gt0 \end{cases} \]
Evaluate \(f(4)\).
Evaluate \(f(4)\).
