(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
