f: (1,7), (2,5), (3,6), (4,7)
is f a function ? if yes state the domain and the range. if no explain why it is not
we know that
A relationship between two variables x and y represent a function, if for one value of x, there is only one value of y
In this problem
For one value of x, there is only one value of y
therefore
Yes, is a function
The domain is the data set (1,2,3,4)
The range is the data set (7,5,6,7)
