Tests Horizontal Vertical Line Test Functions

Will the following graph have an inverse function?

• Yes

• No

What does the vertical line test determine?

• it tests whether the relation is a one-to-one function

• it is not real

• it test the relation

• it tests whether the relation is a function

Is the inverse of this a function?

• Yes

• No

If the codomain is ℝ, the relation in the graph is..

• neither a one-to-one nor an onto function.

• a one-to-one function.

• both a one-to-one and onto function.

• an onto function.

• not a function.

Is this 1 - 1?

• Yes, the original is a function, but the inverse is not.

• No, the original is a not function, but the inverse is.

• No, the original is a function, but the inverse is not.

• Yes, the original and inverse are functions.

What is the best way to describe this relation?

• One-to-One

• Function

• Relation

How do you determine if a relation is a function?

• The vertical line test crosses at least one point on the graph.

• The horizontal line test crosses at least one point on the graph.

• The vertical line test crosses only one point on the graph.

• The horizontal line test crosses only one point on the graph.

Is this a function? Explain.

• Yes; it passes the horizontal line test.

• No; it is not a straight line.

• Yes; it passes the vertical line test.

• No; it is not a smooth curve.

Will the inverse of this function, be a function also?

• yes, it passes the horizontal line test

• no, it fails the horizontal line test

• sometimes, it passes the vertical line test

• can't tell, it fails all tests

Will the inverse of this function, be a function also?

• yes, it passes the horizontal line test

• no, it fails the horizontal line test

• sometimes, it passes the vertical line test

• can't tell, it fails all tests
