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.

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

Please help me!!

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)

Thank You Steve. Now I understand the intersection. Could you please explain the union now.

Ecample: (-1,1)U[0,6]
