Choose the correct answer below.
O A. {x x is an even integer or x = 2 or x = 4}
O B. {x|x is an even integer or x = 3 or x = 5}
OC. {x|x is an odd integer or x = 3 or x = 5}
OD. {xx is an odd integer or x = 2 or x = 4}

Answer:

  • D)  {x: | x is an odd integer or x = 2 or x = 4}

-----------------------------

Given two sets:

  • A = {x: | x is an odd integer}, B = {2, 3, 4, 5}

Both sets include 3 and 5 so the combination is all the elements of the A and two unique elements of the B:

  • A∪B = {x: | x is an odd integer or x = 2 or x = 4}

The matching choice is D.
