$\"\"$

\

(a)

\

The function is $\"\"$ .

\

Rewrite the function as $\"\"$ .

\

Find the inverse function.

\

$\"\"$

\

Interchange the variables $\"image\"$ and $\"image\"$ .

\

$\"\"$

\

Extract square root on each side.

\

$\"\"$

\

Substitute $\"\"$ .

\

The inverse of the function is $\"\"$ . $\"\"$

\

(b)

\

Draw a coordinate plane.

\

Graph the functions $\"\"$ and $\"\"$ .

\

$\"\"$

\

Observe the graph :

\

The functions $\"\"$ and $\"\"$ are symmetric about the line $\"\"$ .

\

$\"\"$

\

(c)

\

The function is $\"\"$ .

\

The domain of a function is all values of $\"\"$ , those makes the function mathematically correct.

\

Since $\"\"$ is a quadratic function, domain is all real numbers.

\

Domain of $\"\"$ is $\"image\"$ .

\

Range of $\"\"$ is $\"\"$ .

\

$\"\"$

\

(d)

\

The inverse function is $\"\"$ .

\

The function under the square cannot be negative.

\

The domain of the $\"\"$ is set of all non negative real numbers.

\

Domain of $\"\"$ is $\"image\"$ .

\

The range of the function $\"\"$ is set all positive numbers.

\

Range of $\"\"$ is $\"\"$ .

\

Note : The range of $\"\"$ is the domain of $\"\"$ .
