(a)
\The function is .
Rewrite the function as .
Find the inverse function.
\Interchange the variables and
.
Cubing on each side.
\Substitute .
The inverse of the function is .
(b)
\Draw a coordinate plane.
\Graph the functions and
for
.
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.
Domain of is
.
Range of the function is all posssible output values.
\Range of the function is non negative numbers.
\Range of the function is also
.
The inverse function is .
The domain of is range of
.
Therefore, domain of is
.
The range of is the domain of
.
Therefore, range of is
.
