We would like to find the -coordinates of all points on the graph that have -coordinate less than or equal to . These points on the graph are indicated by the heavy portion of the line.
Use the graph to solve the equation or inequality. (Note the scales on the axes.) Show your solutions on the graph. Then verify your solutions by solving algebraically.
