For the function
Find the inverse function.
Write down the steps for the function. Reverse the order.
Write the new steps using algebra and inverse notation.
The steps for the original function are:
1) Multiply by
Show that your inverse function is correct. Choose an input number for the function and calculate the output. Use this output as the input for the inverse function. Is your final output the same as your original input?
Substitute a number for
in , then simplify.
Then substitute your answer from
into the inverse function, then simplify.
If your answer for the inverse function is equal to the value you substituted for
in , your inverse function is correct.
