If an endpoint is included—shown by a closed dot, such as in the graph to the right—use = instead of ≤ or ≥ to indicate the number is included. Complete the inequality for the domain. −4 x 4 On a coordinate plane, a graph of an image with a curve and straight line has 2 points. A closed circle appears at (negative 4, negative 2) and an open circle appears at (4, 5).Complete the inequality for the domain. −4 <= or < x <= or < 4
