How do I determine if a function is one-to-one?
The horizontal line test can be used to find out if a function is one-to-one. If you can superimpose a horizontal line onto a graph, you can see if it intersects the graph more than once. The graph isn’t one-to-one if it only intersects at a single point.
What is an example of a one-to-one function?
A one-to-one function is when the answers are never repeated. One-to-one functions produce different answers for each input.
What is a function of a book?
A book is a medium for recording information in the form of writing or images that are bound together and protected by a cover.
Which of the following functions is one-to-one?
An example of a one to one function is what I am talking about. The function f(x) is a one to one function that can be used to produce different outputs for different inputs. For a function to be one to one, it needs to return a range for each element. If x is 1, 7 or 2, f(x) will return 6.
