Which of the following statements are true regarding functions? Check all that apply. A. The horizontal line test may be used to determine whether a function is one-to-one. B. The vertical line test may be used to determine whether a relatio is a function. C. A sequence is a function whose domain is the set of rational numbers. PREVIOUS

Answer 1

Statement A is true.

In the next example, we can see a function that is not one-to-one with the help of the horizontal line test:

Statement B is true.

In the next example, we can see a relationship that is not a function because it doesn't pass the vertical line test

Statement C is false.

A sequence is a function whose domain is the set of natural numbers
