What is the range of the inverse of relation {(1, 7), (2, -4), (5, 6), (2, 8)}?

Inverse:

D: {7, -4, 6, 8}

R: {(1,  2, 5}

Step-by-step explanation:

Function

Domain :D   the input

Range:R    the output

Inverse function :  

Domain:  R  (the output of the function is the input to the inverse)

Range  D  (The output of the inverse is the input of the function

Function

D: {(1,  2, 5}

R: {7, -4, 6, 8}

Inverse:

D: {7, -4, 6, 8}

R: {(1,  2, 5}
