Example: Graphing the Function f(x)=−x3f(x) = -x^3

To graph the function f(x)=−x3f(x) = -x^3, we select xx-values, apply the function to find the corresponding yy-values, and plot the resulting ordered pairs. For example, using the xx-values −2-2, −1-1, 00, 11, and 22 produces the corresponding yy-values 88, 11, 00, −1-1, and −8-8. By plotting the points (−2,8)(-2, 8), (−1,1)(-1, 1), (0, 0), (1,−1)(1, -1), and (2,−8)(2, -8) on a rectangular coordinate system and connecting them, we form the required downward-sloping curve.
