NAND gates and NOR gates are two types of Universal Gates. Represent each equation as a circuit using only a single type of a Universal Gate. I.E$.$ Each answer must contain only NAND gates or must contain only NOR gates. Assume literals are not available in complemented form.

F$($x$,$ y$,$ z$)=$ y$\text{'}$z$\text{'}+$ y$\text{'}$z $+$ x$\text{'}$yz$\text{'}$
