Question

Choose the true statement about the graph of x < 4.

closed circle on 4 and all numbers to the left shaded
open circle on 4 and all numbers to the right shaded
open circle on 4 and all numbers to the left shaded

Answer 1

The circle must be open because we're dealing with the values less than 4 but not including 4. The shading would be to the left, because the values less than 4 are on the left of 4, when you're looking at the x axis.
