Answer 1

Answer:The correct option is d.

Explanation:Domain is the set of all possible inputs or the values of x and the range is value of output or y.

In option a:The given function is

{(−2,−5),(8,10),(0,6),(−2,−9),(0,2)}

Domain = {-2,0,8}

Range = {-9,-5,2,6,10}

Therefore option a is incorrect.

In option b,

The given function is

{(−9,10),(−2,8)}

Domain = {-9,-2}

Range = {8,10}

Therefore option b is incorrect.

In option c,

The given function is

{(−9,−2),(−5,0),(2,8),(6,5),(10,9)}

Domain = {-9,-5,2,6,10}

Range = {-2,0,5,8,9}

Therefore option c is incorrect.

In option d,

The given function is

{(2,0),(−5,−2),(10,8),(6,0),(−9,−2)}

Domain = {-9,-5,2,6,10}

Range = {-2,0,8}

Therefore option d is correct.
