Consider the function below. x -1 0 1 2 f(x) -2 3 8 13 which of the following functions could be the inverse of function f? x -2 3 8 13 q(x) -1 0 1 2 x -2 -3 -8 -13 r(x) 1 0 -1 -2 x -1 0 1 2 p(x) 2 -3 -8 -13 x 1 0 -1 -2 s(x) -2 3 8 13

Look at the original problem.  Its domain is {-1,0,1, 2}, and its range is {-2,3,8,13}.  The inverse function of this given function has {-2,3,8,13} as its domain and {-1,0,1, 2} as its range.

Domain of original function becomes Range of the inverse function.

Ithink it is b and d
