Chapter 8: Q6. (page 403)

Represent the relation as a graph and as a mapping diagram. Then tell whether the relation is a function. Explain your reasoning.
$(- 4, 2), (2, 3), (4, 8), (0, 3), (- 2, 2)$

Short Answer

Expert verified

The given relation isa function.

Step by step solution

Step 1. Given Information.

A relation: $(- 4, 2), (2, 3), (4, 8), (0, 3), (- 2, 2)$

Step 2. Calculation.

Upon graphing our given relation, we will get our required graph as shown below:

The mapping diagram of our given relation would look like:

We know that a relationship will be also a function, when each input in the domain has exactly one specific corresponding output.

Upon looking at our given ordered pairs, we can see that each x-value corresponds to a specific y-value.

Step 3. Conclusion.

The given relation is a function.
