fin. 1.7 Transformations of Functions 73 Identifying a Parent Function In Exercises 21-46, g is related to one of the parent functions described in Section 1.6. (a) Identify the parent function f. (b) Describe the sequence of transformations from f to g. (c) Sketch the graph of g. (d) Use function notation to write g in terms of f. 21. g(x) = 12 - x2 22. 8 (x) = (x L 8)2 23. 8(x) = x3 + 7 24. 8(x) = -x3 - 1
