For each Boolean function:

$f=x(xdarry)>(zo\frac{+}{b}ar(y))$

$((\frac{?}{\text{b}\text{a}\text{r}}(y)darrz)|)$

a$)$ create a truth table;

b$)$ write the full disjunctive normal form and the full conjunctive normal form;

c$)$ provide the geometrical representation or Karnaugh map $($K$-$map$)$;

d$)$ minimize the function.
