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

x is less than 4
and "less than" means to the left, on a number line
there is no "or equal to" part so it is an open circle
