.
Cubing 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.
Domain of is all real numbers.
Range of the function is a set of all real numbers.
The inverse function is .
The range of is the domain of
.
Therefore, domain of is a set of all real numbers.
The range of is the domain of
.
Therefore, range of is a set of all real numbers.
