D = x is a whole number E = x is a perfect square between 1 and 9 F = x is an even number greater than or equal to 2 and less than 9 E∪F is {2,4,6,8} True False

Question

D = x E = x is a perfect square between 1 and 9 F = x E∪F is {2,4,6,8} True False

Answer 1

if 1 and 9 are still considered part of E (they are perfect squares of 1 and 3),they should be considered also in EUF, so it would be false. If in E are just considered numbers BETWEEN 1 and 9, the answer is correct
