Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle {{15}\over{x-2}}+9 &\text{if }\displaystyle x\lt1\\ \\ \displaystyle 3-2 x &\text{if }\displaystyle 1\le x\le4\\\\\displaystyle 5 x ^2-8 x -9 &\text{if } \displaystyle x\gt4 \end{cases} \]
Evaluate \(f(-3)\).
Evaluate \(f(-3)\).
