## To graph: using a graphing calculator.

Expert Solution

### Explanation of Solution

Given information: consider the provided function,

f(x)=41x3

Graph:

Step 1: Open Graphing Calculator from the start menu.

Step 2: Click on the input box and enter the function provided f(x)=4

Step 3: Press Enter.

Step 4: enter 1x3

Hence, the graph so obtained is, b.

To determine

### To calculate: the domain and the range from the graph

Expert Solution

the domain from the graph is [1,3] and the range from the graph is [,] .

### Explanation of Solution

Given information: consider the graph obtained in part a., The domain of the function f is all the x-values of the points on the graph, and the range is all the corresponding y -values.

The x -values have been restricted between 1x3 , therefore, the domain of the graph is [1,3]

the graph obtained in part a. is straight line and has infinite numbers of y values the range is [,]

Hence, the domain from the graph is [1,3] and the range from the graph is [,] .
