Final answer:
To graph the function f(x) = cos(x)/(1+x), input the function into a graphing device or software with an appropriate viewing rectangle. The graph will be a declining curve with values approaching 0 as x approaches infinity.
Step-by-step explanation:
To graph the function f(x) = cos(x)/(1+x), you can use a graphing device or software that allows you to plot functions. The viewing rectangle should be appropriate for the range of x values you want to consider, in this case, 0 to 20. By inputting the function into the graphing device, you will be able to see the graph of f(x), which will be a curve.
On the graph, you can label the axes as f(x) and x. Scale the x-axis from 0 to 20 and the y-axis according to the maximum and minimum values of f(x) within that range. In this case, f(x) ranges from approximately -0.942 to 1.
The graph of f(x) = cos(x)/(1+x) will have a declining curve shape, with values approaching 0 as x approaches infinity. The maximum value on the y-axis will be approximately 1.
