Question

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

Answer 1

Inverse:

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

R: {(1, 2, 5}

(^^He's Correct.)

Answer 2

Inverse:

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

R: {(1, 2, 5}

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}
