Help and explain please

Given:

The function is:

The given function is:

The range of this function is .

To find:

The range of first function.

The domain of second function.

Solution:

Domain is the set of input or x-values and range is the set of output or y-values.

We have,

Here, the x-values are 1, 2, 3 and the y-values are 0, 3, 6.

Therefore, the range of the given function is . Hence, the correct option is C.

The given function is:

           ...(i)

The range of this function is .

Putting in (i), we get

Similarly,

Putting in (i), we get

Putting in (i), we get

The domain of this function is . Hence, the correct option is A.

if you need just tell me and i will come to the rescue.
