(03.01) Consider the two groups listed below. Which statement describes the sets?
• house
complete mailing address

Both (house, complete mailing address) and (complete mailing address, house) are functions.

Step-by-step explanation: A function is a relation in which each element of the domain (x-values) is mapped to one element of the range (y-values).

In the set (house, complete mailing address), the values of "house" would be the domain and the values of "complete mailing address" would be the range.  In order to be a function, each value of "house" would be mapped to only one value of "complete mailing address."  This is true; each house will have only one complete mailing address.  This means it is a function.

In the set (complete mailing address, house), the values of "complete mailing address" would be the domain and the values of "house" would be the range.  In order to be a function, each value of "complete mailing address" would be mapped to only one value of "house."  This is true; each complete mailing address would go with only one house.  This means it is a function.

all it means is function 3

225x²=-4

x²=-4/225

x=±√-4/225
