Where is the inverse function on the TI-84 Plus?

On the TI-84 Plus calculator, to find the inverse function, you can use the "Y=" editor to define your function. Once you've entered your function, press the "2nd" key followed by the "Y=" key to access the "Vars" menu, then select "Y-VARS" and choose "Function." You can find the inverse function by using the "x" variable or applying the "1/x" functionality, depending on the context. For direct inverse calculations, you can also use the "Calc" feature to evaluate the inverse at specific points.
