Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle 8 x ^2+6 x -7 &\text{if }\displaystyle x\le1\\ \\ \displaystyle 8 x +3 &\text{if }\displaystyle 1\lt x\lt4\\\\\displaystyle \sqrt{3 x -3} &\text{if } \displaystyle x\ge4 \end{cases} \]
Evaluate \(f(-5)\).
Evaluate \(f(-5)\).
