Question 975269: Write F∩H and F ∪H using interval notation. Write Ø if set has no solution.

F={z|z<4}
H={z|z>=7}
I came up with an answer of (-infinity, 4) and [7,infinity)
however both answers were in correct

You came up with one answer but two answers were required.
F∩H= Ø
F ∪ H=(-infinity,4)U[7,infinity)
