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?

a.
x -2 3 8 13
q(x) -1 0 1 2

b.
x 1 0 -1 -2
s(x) -2 3 8 13

c.
x -2 -3 -8 -13
r(x) 1 0 -1 -2

d.
x -1 0 1 2
p(x) 2 -3 -8 -13

A.

  x -2 3 8 13

  q(x) -1 0 1 2

Step-by-step explanation:

The inverse function swaps the positions in each ordered pair.

For the function ...

   {(-1, -2), (0, 3), (1, 8), (2, 13)}

The inverse function is ...

  {(-2, -1), (3, 0), (8, 1), (13, 2)} . . . . . matches choice A

both equations and proportions are better.
