Tests Horizontal Vertical Line Test Functions

Give the domain and range. Tell if it is a function.

• D: {-4, -2, 0, 2}
  R: {-2, -2, 1, 1}
  Function

• D: {-4, -2, 0, 2}
  R: {-2, 1}
  Function

• D: {-4, -2, 0, 2}
  R: {-2, -2, 1, 1}
  Not a Function

• D: {-4, -2, 0, 2}
  R: {-2, 1}
  Not a Function

Which is true regarding the horizontal line test?

• The test is used on the original graph to see if that graph is a function

• The test is used on the original graph to see if it is an one-to one function

• The test is used on the inverse graph and can only touch the graph in two places to pass the test.

• The test is used on the inverse graph to see if it is an one-to one function

A quadratic graph fails the horizontal line test, so its inverse is not a function.

• True

• False

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

• yes

• no

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

• yes

• no

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

• yes

• no

• yes

• no

• Function

• Not a function
