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.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
