Question

Use the method of adding y-coordinates to graph each function.

$f\left(x\right)=x+\cos x$

Short answer

The required graph is

Step-by-step solution

Step 1. Given Information

The given function is$f\left(x\right)=x+\cos x$

Step 2. Explanation

Plot the graph of the component functions in the same coordinate system.

Next, select different values for x to plot the points on the graph of $f_1\left(x\right)and{f}_2\left(x\right)$,

Step 3. Graph

Plot the graph by using the points in the table.
