Hey everyone!
First off thank you to reddit user (u/ritvikthebeast) for notifying me of this issue, as a result I made a program which should work on handheld to fix this.
On the Ti handheld calculator, it cannot solve for a cubic inverse function even if you give it in the form a(x-b)3 + c which is perhaps due to the calculator expanding it immediately after you input it? (just a theory)
Anywayyy, the link to the youtube video I made is below, in this I discuss the issue as well as provide the syntax and code for the program to fix this problem

I have also attached the link to the google drive below which contains a file containing the program

Enjoy! and I hope this makes doing vce methods just a bit less painful 😃
IMPORTANT !!!!This only works for stuff which has the same shape as x3 (i.e. can be written into the form a(x-b)3+c) if the cubic has local maxima or minima this will NOT work!!!!
