Question 544727
{{{y=root(3,x)}}} is the original function
{{{y=root(3,x)}}} <---> {{{y^3=x}}}
To find the inverse function we swap x for y
{{{x^3=y}}}
{{{ graph( 300, 300, -1, 9, -1, 9,x^(1/3),
x^3) }}} Both functions have the set iof real numbers for domain and range.
(I just could not get {{{y=root(3,x)}}} (red function) to plot for negative x values).
They are each other's reflection on the {{{y=x}}} diagonal line.
