(2 points) claim: figure 3 contains a hamiltonian circuit. find an
algorithm or route (e. g. x-z-y-w) that is a hamiltonian circuit or
state why one cannot exist.

This is a rational expression because the denominator contains a variable. this is a polynomial with 3 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 4 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 4 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 3 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 5 terms.
