Daniella, draw a number line like the one below. Draw an open circle at -2 and another at 4. Then, shade in the space between -2 and 4. This will represent the interval -2 < x < 4 or (-2, 4)

That's right, Daniella...between the two endpoints. It's a little hard to draw on here, but it seems that you have the idea. Thanks for your patience and understanding.
