what is the value for b that would make the following into a function {(1.2)(2,3)(4,b)(6,8)}



In order for the given set \(\{(1,2), (2,3), (4,b), (6,8)\}\) to be a function, every input (x-value) must correspond to exactly one output (y-value). This means that each x-value in the set must be unique.

Looking at the x-values: 1, 2, 4, and 6, we can see that each one is distinct, so there is no conflict with the x-values. Therefore, the value of \(b\) can be any real number because no x-value is repeated, and there is no restriction on the corresponding y-values.

Thus, the value of \(b\) can be **any real number** for this to be a function.

1. What is the definition of a function in terms of sets of ordered pairs?
2. How do you check if a given relation is a function?
3. Can a function have repeated y-values for different x-values?
4. What is the vertical line test, and how does it relate to functions?
5. What happens if an x-value in a set has more than one corresponding y-value?

**Tip:** To verify if a relation is a function, always check that each x-value maps to only one y-value.
