Represent -2 < x < 4 on the number line.

This question asks to represent a double inequality on a number line. The inequality is -2 < x < 4. This can be read as two separate inequalities: x > -2 and x < 4. - The `x > -2` part means x is any number larger than -2. On a number line, we indicate this with an open circle at -2 (because it's not "greater than or equal to") and shading to the right. - The `x < 4` part means x is any number smaller than 4. We indicate this with an open circle at 4 and shading to the left. - Combining them means we want the numbers that satisfy both conditions, which is the region between -2 and 4. So, we draw an open circle at -2, an open circle at 4, and connect them with a solid line.
