Use integral properties to write

${\displaystyle \underset{-3}{\overset{4}{}}}f(x)dx+{\displaystyle \underset{4}{\overset{7}{}}}f(x)dx-{\displaystyle \underset{-3}{\overset{-1}{}}}f(x)dx$

as a single integral ${\displaystyle \underset{a}{\overset{b}{}}}f(x)dx.$

$($A$.){\displaystyle \underset{-3}{\overset{4}{}}}f(x)dx$
