Question 433115
To find an inverse, first change the f(x) to y.  Then change the x to y and the y to x.
{{{y=(x+6)^3}}}
{{{x=(y+6)^3}}} Then solve for y. First take the third root of both sides.
{{{cubert(x)=y+6}}} Then subtract 6 from both sides.
{{{cubert(x)-6=y}}} Then change the y into {{{f^-1(x)}}}.
{{{f^-1(x)=cubert(x)-6}}}
