Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle -7 x ^2-9 x -4 &\text{if }\displaystyle x\lt3\\ \\ \displaystyle 7-9 x &\text{if }\displaystyle 3\le x\le10\\\\\displaystyle \sqrt{x-3} &\text{if } \displaystyle x\gt10 \end{cases} \]
Evaluate \(f(-3)\).
Evaluate \(f(-3)\).
