A. B={4,5,6,7} B. B={4,5,6,7,…} C. B={3} D. B={3,4,5,6,…} E. B={3,4,5,6,…100} F. B={3,4,5,6} G. B=∅

Answer 1

Answer: {3, 4, 5, 6, ...}

Step-by-step explanation

The symbol x∈N means "x is a natural number". The set of natural numbers is {1,2,3,4,5,6...} basically positive whole numbers.

We're further told that x≥3 so we'll start at 3 and count upward.

So that's how we arrive at {3, 4, 5, 6, ...}

The three dots means to continue that pattern forever.
