Step 1:

The functions are $\"image\"$ and $\"image\"$ .

(a)

Find the value of $\"image\"$ .

$\"\"$ $\"image\"$

All possible values of x is domain of the function.

The function $\"image\"$ is defined for all values of x .

The domain of $\"image\"$ is $\"image\"$ .

Step 2:

(b)

Find the value of $\"image\"$ .

$\"\"$

$\"image\"$

All possible values of x is domain of the function.

The function $\"image\"$ is defined for all values of x .

The domain of $\"image\"$ is $\"image\"$ .

Step 3:

(c)

Find the value of $\"image\"$ .

$\"\"$

$\"image\"$

All possible values of x is domain of the function.

The function $\"image\"$ is defined for all values of x .

The domain of $\"image\"$ is $\"image\"$ .

Step 4:

(d)

Find the value of $\"image\"$ .

$\"\"$

$\"image\"$

All possible values of x is domain of a function.

The denominator of a function should not be zero.

$\"image\"$

The domain of $\"image\"$ is $\"image\"$ .

Solution:

(a) The domain of $\"image\"$ is $\"image\"$ .

(b) The domain of $\"image\"$ is $\"image\"$ .

(d) The domain of $\"image\"$ is $\"image\"$ .
