Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle -3 x ^2-3 x -7 &\text{if }\displaystyle x\lt-3\\ \\ \displaystyle 3-3 x &\text{if }\displaystyle -3\le x\le5\\\\\displaystyle \sqrt{3 x +9} &\text{if } \displaystyle x\gt5 \end{cases} \]
Evaluate \(f(-5)\).
Evaluate \(f(-5)\).
