True or false: If $f$ is continuous everywhere except $x=3,$ then in order to compute ${\displaystyle \underset{1}{\overset{}{}}}f(x)dx$ it is necessary to write it as ${\displaystyle \underset{1}{\overset{}{}}}f(x)dx={\displaystyle \underset{1}{\overset{3}{}}}f(x)dx+{\displaystyle \underset{3}{\overset{}{}}}f(x)dx$ True False
