If \(P = {x : -2 < x < 5}\) and \(Q = {x : -5 < x < 2}\) are subsets of \(\mu = {x : -5 \leq x \leq 5}\), where x is a real number, find \((P \cup Q)\).
\({x : -5 < x < 5}\)
\({x : -5 \leq x \leq 5}\)
\({x : -5 \leq x < 5}\)
\({x : -5 < x \leq 5}\)
Explanation
\(P = {x : -2 < x < 5}\) and \(Q = {x: -5 < x < 2}\)
\((P \cup Q) = {x : -5 < x < 5}\)
