What is the test to determine if a function has an inverse that is also a function?

• Horizontal line test

• Vertical line test

• Heidelberg Uncertainty Test

• Obi Wan Kenobi Test

Look at the graph. Is the relation a function?

• yes because it passed the vertical line test.

• no because it failed the vertical line test.

• Function because it passed the vertical line test.

• Not a Function because it failed the vertical line test.

• Function because it passed the vertical line test.

• Not a Function because it failed the vertical line test.

Use the horizontal line test to determine if the function has an inverse function.

• yes

• no
