Digital Logic Design: Function Decomposition

Given: fxy.z)- xy*xz-yz. gxy) - xy, and pxy)- x*y How many levels does f above have? Give f with z factored out (no blanks and answer in alphabetic order How many levels does f have with z factored out? Use functional decomposition to give f as a function of g. p. and z How manylevels does the functionalily decomposed function have
