as you already know, to get the inverse, we first do a quick switcharoo on the variables, and then solve for "y",
[tex]\bf y=3x^3-5\qquad \stackrel{inverse}{\underline{x}=3\underline{y}^3-5}\implies x+5=3y^3 \\\\\\ \cfrac{x+5}{3}=y^3\implies \sqrt[3]{\cfrac{x+5}{3}}=\stackrel{f^{-1}(x)}{y}[/tex]

When they say inverse it’s kind of the operation equation or the numbers
