Finding Inverses

What does it mean if a table is one-to-one?

(*Hint: Look in your notes)

We use the __________ ______ ______ to determine if an inverse is a function.

Will the inverse of this function, be a function?

• No
• Yes
• No way to tell

Suppose you are given a table of values. When creating a table for the inverse graph you must...?

• Switch the x and y
• Solve for x
• Plot the coordinates
• Potato

Are these inverse functions?

• yes
• no
• no way to tell

When finding the inverse of a relation, 
1st you replace f(x) with y
2nd switch the x's and y's
What do you do next?

• solve for y
• replace y with f^-1(x)
• solve for x
• find the greatest common factor

Is the function one-to-one?

• No

• Yes

Is the inverse of this a function?

• Yes

• No
