Option A. x 7 8 9 10 y -49 -56 -63 -70 is the right answer.
Step-by-step explanation:
The inverse of a function means that the input becomes the output of the function and the output becomes input. When the function is given in the form of ordered pairs, the fiirst element of each ordered pair represents input and second element represents the output.
So, for given function: {(-49,7), (-56,8), (-63,9), (-70,10)}
The inverse will be:
{(7, -49), (8,-56), (9,-63), (10, -70)}
Hence,
Option A. x 7 8 9 10 y -49 -56 -63 -70 is the right answer.
