2.2.1 Transforming Linear Functions − Worksheet (continued)
Example 4: Graph f ( x ) and g ( x ). Then describe the transformations from the graph of f ( x ) to the graph of g ( x ). 13. f(x ) = x , g ( x ) = 2 x − 2 14. f ( x ) = = + f x x g x x ( ) , ( ) 1

Example 5: 17. For large parties, a restaurant charges a reservation fee of $25, plus $15 per person. The total charge for a party of x people is f ( x ) = 15 x + 25. How will the graph of this function change if the reservation fee is raised to $50? if the per-person charge is lowered to $12?
