Previous Activity: Print this activityContents: Domain, range, asymptotes, rational functions and intercepts.Introduction: In this activity you will explore the different transformations of the graphs of
rational functionsRequired material: Activity 2.14 and laptop with graphmaticaEstimated time: 50 minutesDelivery form: You will hand in this activity individuallyInstructions: Read the instructions carefully, write out the problems, show complete procedure
and mark the final answer.Evaluation criteria: The activity will be graded by considering the number or correctly answers and
the procedure organization and neatnessHomework: Exercises 1-8 on page 350

unit right.
3.( ) The function moves 3 units up and 4 units right.
4.( ) The function moves 1 unit down, reflection over x-axis and moves 2
units right.
5. ( ) The function moves 5 units up and moves 2 units right.
6.( ) The function moves 5 units up and moves 2 units left.
7.( ) The function moves 2 units up and moves 5 units left.
8. ( ) The function moves 4 units up and moves 3 units left.
