Pro jaké hodnoty reálných parametrů \(a\), \(b\), \(c\), \(d\), \(e\) a \(f\) budou uvedené matice navzájem inverzní?
\[
\left (\array{
1& 0 & 0\cr
0 & 1 & 1
\cr
a& b & c} \right ),
\left (\array{
d& e & f\cr
-1 & 1 & -1
\cr
1& 0 & 1} \right )
\]
\(a=-1\), \(b=0\), \(c=1\), \(d=1\), \(e=0\), \(f=0\)
\(a=1\), \(b=0\), \(c=1\), \(d=-1\), \(e=0\), \(f=1\)
\(a=-1\), \(b=0\), \(c=-1\), \(d=1\), \(e=0\), \(f=0\)
\(a=1\), \(b=0\), \(c=-1\), \(d=-1\), \(e=1\), \(f=0\)
