(Section 1.3: Basic Graphs and Symmetry) 1.3.24 3. Power functions with rational powers of the form even odd . Let fx () = x N / D , where N is an even and positive integer, and D is an odd and positive integer. = x 2/3 = x 6/3 = x 2 If N D is a proper fraction, then the graph of f resembles the graph on the left . Examples: = x 2 3 or x , = x 4 7 or x 4/7 . If N D is an improper fraction, then the graph of f resembles the graph on the right , where = x 6 3 = x = x 2 . 4. Power functions with rational powers of the form even even . Let = x N / D , where N and D are both even and positive integers. Different interpretations of
