Asked by Brittani
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.
