Question

For the given set of ordered pairs, determine whether a function could be defined for which the input would be an x-coordinate and the output would be the corresponding y-coordinate. if a function cannot be defined in this manner ,explain why .

{ (1,1),(2,2),(3,3),(4,4),(5,5)

Answer 1

Perhaps I misunderstand the question but the function here is x=y. The pairs here are all equal, meaning that whatever number x is, y is the same. Therefore the function would be

 

y(x) = x , y as a function of x is equal to x.
