(a)
\The function is
.
Rewrite the function as
.
Find the inverse function.
\
.
Interchange the variables
and
.
.
Squaring 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 functions
and
are symmetric about the line
.
(d)
\The function is
.
The domain of a function is all values of
, those makes the function mathematically correct.
The function under the square cannot be negative.
\
Therefore, Domain of
is
.
Range of the function
is a set of all non negative real numbers.
Range of
is
.
The inverse function is
.
Note : The range of
is the domain of
.
Therefore, domain of
is
.
Note : The range of
is the domain of
.
Therefore, range of
is
.
