If P(x) is a predicate with domain D, the truth set of P(x) is denoted ___. We read these symbols out loud as ____.

To determine

To fill in the blank “If P(x) is a predicate with domain D, the truth set of P(x) is denoted_______, we read these symbols out loud as________.”

Explanation of Solution

Given:

If P(x) is a predicate with domain D, the truth set of P(x) is denoted_______, we read these symbols out loud as________.

If P(x) is a predicate and x has domain D, the truth set of P(x) is the set of all elements of D that make P(x) true when they are substituted for x. The truth set of P(x) is denoted {xD|P(x)}
