How to graph the inverse of a function with TI's
Free Online Help for Common Graphing Calculator Procedures
Many of us go out to the store and buy a graphing calculator
, then when we get home, we wonder what next? The purpose of these tutorials is the answer that question!
|This first step is not necessary. The only purpose of step 1 is to
graph the original function. If you only want to draw the graph of the inverse of the function skip to steps 2 and 3
Step 1) Graph a function as you would normally
Click on the 'y=' button and then type any math function (we will use y = x² +2x +1 in our example)
Press the graph button and you will see the function graphed (in our case a parabola's graph )
|Step 2) To graph the inverse of whatever function is currently graphed. Press the following sequence of buttons
- 2nd button (on top left of graphing calculator)
- the 'DRAW' button which is immediately under the STAT in the TI-83 and TI-84 (at this point you should see the image on the right)
- Scroll down to 8 "DrawInv" which of course stands for drawing the inverse of the function
|Step 3) press 'enter'
Enter the function whose inverse you want to draw, which for us is this equation of a parabola :y =x² + 2x +1
|Press 'enter' then hit 'graph' to see the graph!
|To clear the graph of an inverse from your Ti 's graph screen
, press the following four buttons
