Okay, here we have this:
Considering the provided function, we are going to plot five points on the graph and use them to graph the function with the help of a graphing calculator, then we get the following:
To calculate the 5 points we will evaluate the function at x=0, 1, 2, 3 and 4, then we have:
x=0:

x=1:

x=2:

x=3:

x=4:

Finally then we will graph these points and use them to graph the function, and the graph looks like this:
