If $f(2-x) = f(2+x)$ and $f(4-x) = f(4+x)$ and $\displaystyle \int_{0}^{2}f(x)dx = 5$ . Then $\displaystyle \int_{0}^{50}f(x)dx =$

$\displaystyle \int_{0}^{50}f(x)dx =125$

How did that happen?

well you can let

f(x) = 5/2

which satisfies all of the properties

then

$\begin{align*}\int_{0}^{50} f(x) \, \mathrm{d}x &= 50 \times \frac{5}{2}\\&=125\end{align*}$
