Exercise 2 Page 55

To draw a graph using a calculator, first press the $\boxed{\text{Y=}}$ button. After that, enter the function in ${\text{Y}}_1.$

To draw the graph, press $\boxed{\text{GRAPH}}.$ If the graph does not show up, you might have to change the window settings.

Finally, using the calculator again, we can determine five ordered pairs. By pushing $\boxed{2\text{ND}}$ and $\boxed{\text{GRAPH}},$ we get a table of values for whole number inputs of $x.$
