Hello, I have been trying to do my math homework for a few hours now and can not figure out how to find the indicated intersection or union in interval notation.

Question

Example: (-1,5)n[0,8)

Please help me!!

Steve · Answer

Draw two number lines, one under the other (-1,5) extends from -1 to 5 underneath, [0,8) extends from 0 to 8 The intersection is just where the intervals overlap: [0,5)
