It can be useful when evaluating a function to create a table with the equation evaluated at different points. The values are calculated by replacing x in the equation with the desired value. For example, if we want to know what is the value of the function at x=2 we perform the following calculation
[tex]\frac{5}{5}(2)-1=(1)(2)-1=2-1=1[/tex]
So, creating the table we get the following
With those values, we can construct the next graph
