To determine

## Draw the graph of f,g and f+g on a common graph

Expert Solution

### Explanation of Solution

Given information : the function is

f(x)=1x4,g(x)=1x29

Graph : Sketch the graph using graphing utility.

Step 1: Press WINDOW button to access the Window editor.

Step 2: Press Y= button.

Step 3: Enter the expression f(x)=1x4,g(x)=1x29 which is required to graph.

Step 4: Press GRAPH button to graph the function.

The graph is obtained as:

Interpretation : On graph the green line shows the f(x)

And the blue line shows the g(x)

And the brown line shows (f+g)(x)
