For each function graphed below state whether it is one-to-one

The term one to one relationship actually refers to relationships between any two items in which one can only belong with only one other item. In a mathematical sense, these relationships can be referred to as one to one functions, in which there are equal numbers of items, or one item can only be paired with only one other item. The name of a person and the reserved seat number of that person in a train is a simple daily life example of one to one function. If you are curious about what makes one to one functions special, then this article will help you learn about their properties and appreciate these functions. Using solved examples, let us explore how to identify these functions based on expressions and graphs. A normal function can actually have two different input values that can produce the same answer, whereas a one to one function does not. One to one function is a special function that maps every element of the range to exactly one element of its domain i. A function that is not one-to-one is called a many-to-one function. A one to one function is also considered as an injection , i. Let us visualize this by mapping two pairs of values to compare functions that are and that are not one to one. In the Fig a which is one to one , x is the domain and f x is the codomain, likewise in Fig b which is not one to one , x is a domain and g x is a codomain. In Fig a , for each x value, there is only one unique value of f x and thus, f x is one to one function. In Fig b , different values of x, 2, and -2 are mapped with a common g x value 4 and also, the different x values -4 and 4 are mapped to a common value Thus, g x is a function that is not a one to one function.

As we have seen in examples above, we can represent a function using a graph. Graphs display many input-output pairs in a small space. The visual information they provide often makes relationships easier to understand. We typically construct graphs with the input values along the horizontal axis and the output values along the vertical axis. If the function is defined for only a few input values, then the graph of the function is only a few points, where the x -coordinate of each point is an input value and the y -coordinate of each point is the corresponding output value.

In our last section, we discussed how we can use graphs on the Cartesian coordinate plane to represent ordered pairs, relations, and functions. In this section, we will dig into the graphs of functions that have been defined using an equation. Our first task is to work backwards from what we did at the end of the last section, and start with a graph to determine the values of a function. After determining these values, compare your answers to what you would get by simply plugging the given values into the function. We can also just evaluate the function directly. The examples above were graphs of functions, but in the last section we talked about graphing relations and not just functions. However, functions are going to be the focus of what we work with in this course so this brings us to an important question: how do we know if a graph represents a function? Based on this, we use what's called the vertical line test to determine if a graph represents a function or not. This test helps us identify from the graph of a function if there's anywhere that a single input may have two outputs.

A: To determine if the graph represents a function or not, perform the vertical line test. If there is any such line, the graph does not represent a function.
