Consider the function

Need to find an approximate viewing window for the above function for x-values between

Since the y-view should include the outputs obtained from the inputs between,

So use table with some or all of the integers through 3 to find corresponding y-values

x		points
0
2
3

These evaluations indicate that the y-view should include value from 0 to 59.

So, choosing the window gives the graph of the function.
