The graphing calculator can be supplied in several methods to inspect your work** when you are managing inverse functions.You are watching: How to find inverse function on ti 84**

A quick way to identify if her algebraic inverse prize is exactly is to:

Example: Is the station of a function? because this parabola does no pass the horizontal line test , the inverse will certainly not be a function. | The red lines will not show up on the calculator. |

A quick way to identify if her algebraic inverse prize is exactly is to:

**a.) go into your starting role in Y1. B.) get in your algebraic inverse answer in Y2. C.) enter Y1(Y2) in Y3. (composition of functions) d.) GRAPH e.) if Y3 to produce the graph the the identity function, y = x, your algebraic inverse answer is correct.**use the calculator to recognize if her algebraic inverse prize is correct. Method 2:

**.**The graph of the inverse will certainly appear.

**If you wish to usage this attribute to check an algebraic answer, a.**go into the original function into Y1.

**b.**DrawInv Y1 (must be done

**before**entering her algebraic answer)

**c.**solve for the inverse algebraically ~ above a item of paper.

**d.**enter your algebraic answer because that the inverse right into Y2 with the bubble computer animation

**(in prior of Y2), and also hit GRAPH. e.**If your algebraic prize is correct, the bubble computer animation will monitor the station graph drawn by the calculator.

Use the table attribute of the calculator to verify the "swapping" that x and also y values between functions and their inverses.

3. | use the calculator to inspection the relationship in between the x and also y worths of functions and inverses. See more: 3/10 = 30/100 ? Fraction Calculator: 30/100 |
