Can you find an inverse function for the function f ( x ) = | 3 x + 4| ? Why or why not? For every function f and its inverse, f 1 it is true that f [ f 1 ( x )] = x and f 1 [ f ( x )] = x . Show that this is true for each pair of inverse functions. 39. f open parenthesis x close parenthesis equals 2 x plus 3 over 2 to the comma power f to the 1 open parenthesis x close parenthesis power equals 1 over 2 x 3 over 4 40.
