Step 1:

\

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

\

(a)

\

Find the value of $\"\"$ .

\

$\"\"$

\

All possible values of x is domain of the function.

\

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

\

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

\

(b)

\

Find the value of $\"\"$ .

\

$\"\"$

\

All possible values of x is domain of the function.

\

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

\

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

\

(c)

\

Find the value of $\"\"$ .

\

$\"\"$

\

All possible values of x is domain of the function.

\

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

\

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

\

(d)

\

Find the value of $\"\"$ .

\

$\"\"$

\

All possible values of x is domain of a function.

\

The denominator of a function should not be zero. \ \

\

$\"\"$

\

The domain of $\"\"$ is $\"\"$

\

Solution:

\

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

\

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

\

(c) The domain of $\"\"$ is $\"\"$ .

\

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