is it possible to plot the inverse of a function and the example was: f(x) = x^3 + x^2 +1?

Can you provide a link, or name of the thread ?

Function and its inverse are mirror image of each other, in the line y=x

Since we cannot "flip" the calculator, the next best thing is to rotate plot.
For shape of f^-1(x), plot -f(x), then rotate plot, 90° counter-clockwise.

note: rotated "x-axis" numbers, if shown, required a sign flip.
