Question 687923: Please help.
Is the following relation a function? (yes/no)
{{(-3,2),(2,-3),(3,2)(4,-3)(1,-3)}}
Thank you
Answer by fcabanski(1391)   (Show Source):
You can put this solution on YOUR website! For a relation (a set of (x,y) coordinates) to be a function, each x must correspond to only one y.
In {{(-3,2),(2,-3),(3,2)(4,-3)(1,-3)}} each x has only one y, so this is a function.
Hope the solution helped. Sometimes you need more than a solution. Contact fcabanski@hotmail.com for online, private tutoring, or personalized problem solving (quick for groups of problems.)
