Section 1.2 In Exercises 17-22, write a function g whose graph represents the indicated transformation of the graph of f. Use a graphing calculator to check your answer. (See Example 3.) 17. Ax) = x + 2; vertical stretch by a factor of 5 20. f(x) = x + 3| ; horizontal stretch by a factor of 4 ANALYZING RELATIONSHIPS In Exercises 23-26, match the graph of the transformation of f with the correct equation shown. Explain your reasoning. A. y = 2f(x) B. y = f(2x) C.y = f (x+ 2 ) D. y = f(x) +2 23. Ay 24. Ay 25. Ay 26. Ay Write a function g whose graph represents the indicated transformations of the graph of f. (See Example 4.) 28. f(x) = x; translation 3 units down followed by 31. f(x) = 3 a vertical shrink by a factor of } 8 x 34. Identify and correct the error in writing the 35. MAKING AN ARGUMENT Your friend function g whose graph represents the indicated claims that when writing a function whose graph transformation of f (x). represents a combination of transformations, the X f(x) = x: translation order is not important. Is your friend correct? 6 units down followed bya Justify your answer. vertical stretch bya factor of 5 g (x) = 5x -6
