Given the sets A\displaystyle {A}A and B\displaystyle {B}B expressed in interval notation, find A∩B\displaystyle {A}\cap{B}A∩B.
A=(−∞,−2)∪(8,+∞)\displaystyle {A}={\left(-\infty,-{2}\right)}\cup{\left({8},+\infty\right)}A=(−∞,−2)∪(8,+∞)
B=[−84,78]\displaystyle {B}={\left[-{84},{78}\right]}B=[−84,78] \displaystyle
A∩B=\displaystyle {A}\cap{B}=A∩B=
