Section 4.3 Worksheet Name: ___________________________________ Period: _____________________ Highland Park High School Algebra 1 Graphing Linear Functions Graph and describe the difference between the graph and its parent function f(x). 1. = + 5 2. = − 3 3. ℎ = + 2 4. = − 1 5. = 2 6. = −4 ! 7. ℎ = ! ! 8. = − ! 9. = 2 − 1 10. The number of hours people in the United States spent playing video games each year from 1998 to 2001 can be modeled by the function = 11.9 + 46.4 where x is the number of years since 1998. a. Graph the function and identify it’s domain and range. b. Find the value of when = 2. Explain what the solutions means in this situation. c. Find the value of when = 60. Explain what the solutions means in this situation. 11. A pool membership during the summer costs $7 per week. The total cost of membership is given by the function = 7. The pool also rents out lockers for $2 per week. The total cost of membership and a rental is given by = 9. a. Graph both functions on the graph provided. How does the graph of f compare to the graph of g. b. What is the difference between a 12-week membership if you get a locker and if you don’t? Explain how you got your answer.
