Final answer:
To find h(b) from the set h, we look for the pair where b is the first element. In the given set, that pair is (b,e), so h(b) equals e.
Step-by-step explanation:
The question asks to find the value of h(b) from the given set h. In mathematics, when h is defined as a set of ordered pairs, the expression h(x) refers to the second element in the pair where the first element is x. Therefore, to find h(b), we need to locate the pair where b is the first element, and then identify the second element in that pair.
In the given set h = { (a,g), (b,e), (c,b), (d,z) }, the pair with b as the first element is (b,e). Thus, h(b) = e.
