Question 674954
f(x) = {{{4x^3-11}}}
...
To find the inverse, {{{f^-1}}}(x), solve for x and substitute the x variable for y in the final equation.
y = {{{4x^3-11}}}
y + 11 = {{{4x^3}}}
{{{(y+11)/4 = x^3}}}
{{{root(3,((y+11)/4)) = root(3,x^3)}}}
{{{root(3,((y+11)/4)) = x}}}
...
{{{f^-1}}}(x) = {{{root(3,((x+11)/4))}}}
