Square Root & Quadratic Inverses

What does it mean to find the inverse of a function?

• the x's and y's are switched
• the x's and y's are divided by 2
• the x's and y's are made negative
• the x's and y's are the same

Are the relations inverses?

• yes

• no

Which is the inverse of the table?

• 
• 
• 
• 

Are the blue and red graphs inverse functions?

• Kind of... the graphs reflect over y = x; however the quadratic is invertible without restriction on the domain.

• No, they do not reflect over the line y = x.

• Yes, the functions reflect over the line y = x.
