Hello! I'm hoping this is the correct sub-forum for set related questions? This is a question from my discrete structures course:
Write the following as a single set using the set-roster notation. You may use elipses (...) if necessary.
{X∈Z∣x≤−10orx≥5}∪{x∈Z−∣x=2yforsomey∈Z}
Since 'union' includes elements from both sets, would it be correct to say that the above written as a single set: {(−infinity,...,−10),(5,...infinity)}
Thank you!
