Question

Which of the following numbers belong to the set of complex numbers AND The set of imaginary numbers? Select all that apply.

Answer 1

To be both complex and imaginary, the answer would have to include "i" as well as have the form "a + bi". The first example, 3i - 5, fits. This would look to be the only example that does fit. The negative square root of 14 would be imaginary, but not complex.
