Determine if the relations is a function and describe the pattern
Yes it is a function, input goes up 1 and output goes up by 15
Yes it is a function, input goes up 15 and output goes up by 1

Not a function, input goes up by 15 and output goes up by 1
Determine if the relation is a function
Not a function, each input has more than one output
Yes it is a function, because each input has exactly on output
Not a function, input is equal to output
