ANSWER and EXPLANATION
We want to order the functions from widest to narrowest:
To do this, we have to plot the graphs of the functions by using a table of values.
Let us find the values of the functions for values of x = -2, 0, 2
For the first function:
Hence, its table is:
For the second function:
Hence, its table is:
For the third function:
Hence, its table is:
Now, let us plot the graphs of the functions:
Therefore, from the graph, we see that the order of the functions from widest to narrowest is:
