I plugged x=1 through x=7 all of them was false. Let P(x) be the statement "(x 21)". If the domain consists of the integers, what is the truth value of ax:P(x)? "A" is the conjunction notation. O True O False 6 or 7 why they pick these value? Let P(x) be the statement "(x 21)". If the domain consists of the integers, what is the truth value of vx:P(x)? "v" is the disjunction notation. O True O False help me with this one. thanks.
