$\"\"$

(a)

The function are $\"\"$ and $\"\"$ .

Find the domain of $\"\"$ .

All possible values of x is the domain of the function.

Since the function is a rational function, the denominator should not be the zero.

$\"\"$

Thus, the domain of the function $\"\"$ is all possible values of x except $\"\"$ and 0.

Find the domain of $\"\"$ .

Since it is a linear function, the domain is all real values of x.

$\"\"$

(b)

The function $\"\"$ .

Simplify the function.

$\"\"$

Since the function is a linear function, there is no vertical asymptote.

$\"\"$

(c)

Completed table is :

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$

(d)

Observe the above table of values :

The functional values of $\"\"$ and $\"\"$ , $\"\"$ and $\"\"$ .

Thus, the function differ at $\"\"$ , where f is undefined. $\"\"$

(a)

The domain of the function $\"\"$ is all possible values of x except $\"\"$ and 0.

The domain of $\"\"$ is all real values of x.

(b)

None.

(c)

Completed table is :

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

(d) The functions f and g differ at $\"\"$ , where f is undefined.
