Applying and Analyzing Functions

Is this graph 1-1?

• Yes

• No

Use the graph to determine whether the inverse of f is a function. Explain your reasoning.

• The inverse is not a function because f does not pass the horizontal line test.

• The inverse is a function because f does not pass the horizontal line test.

• The inverse is not a function because f passes the vertical line test.

• The inverse is a function because f passes the vertical line test.

Is this a one-to-one function?

• yes

• no

The relation in the graph is..

• a function but not a one-to-one function.

• a one-to-one function.

• not a function

Will the inverse of this function, be a function?

• no

• yes

• no way to tell

If a function's inverse is also a function, what is true about the original function.

• It has an inverse

• It is one-to-one

• It passes the diagonal line test

• It is two-to-one

Is this function one to one?

• No, because the function does not pass the vertical and horizontal line test.

• Yes, because the function does not pass the vertical and horizontal line test.

• There is no way to tell.

A function has an inverse function if...

• It passes the Vertical Line Test

• It fails the Horizontal Line Test

• It passes the Horizontal Line Test

• It fails the Vertical Line Test

Determine which function is one-to-one?

• 
• 
• 
• 

What is the best way to describe the relation?

• One-to-one function

• Function

• Relation
