Applying and analysing functions

Is this graph 1-1?

• Yes

• No

Is the inverse of the graph a function?

• 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.

Use the horizontal line test to determine which function is invertible.

• 
• 
• 

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

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.
