EOC Gallery Walk Part 2 (2nd Semester)

The surface area of a cube depends on the length of each side. The length is represented by the x-axis, and the surface area is represented on the y-axis. The student graphed the equation and got the graph to the left. For which values of the domain and range does this graph make sense?

• all real numbers
