My substitute teacher gaves us a worksheet that asks us to do problems we've never had before. How do I do unions and intersections on a number line using inequalities? Is there a formula for this?

Example: A intersects C

A={x|x>-3}

C={x|x greater than or equal to 0}

Example 2: A union C

A and C equal the same as above.
