WebEach number line in the coordinate plane represents the set of real numbers. If you want to graph complex numbers, you need to use the complex plane where the x-axis is the real number portion of a complex number and the y-axis becomes the imaginary component. WebThe blue ray begins at x = 4 x = 4 and, as indicated by the arrowhead, continues to infinity, which illustrates that the solution set includes all real numbers greater than or equal to 4. Figure 2 We can use set-builder notation : { x x ≥ 4 } , { x x ≥ 4 } , which translates to “all real numbers x such that x is greater than or equal ...
