To draw: a graph by using a graphing calculator.
Given information: consider the provided function,
Step 1: Open Graphing Calculator from the start menu.
Step 2: Click on the input box and enter the function provided
Step 3: Press Enter.
Step 4: enter .
Step 5: press enter.
Hence, the graph so obtained is,
To calculate: the domain and the range from the graph
the domain from the graph is and the range from the graph is .
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 , therefore, the domain of the graph is [-2,5]
From the graph, the function cuts the y -axis at y = 0 and at y = 25, the function cuts the extend of the domain, therefore, the range is
Hence, the domain from the graph is and the range from the graph is .
