A function is described as a machine in which it consists of a input and output

2. What is the relationship between x and y?

For example, the rule

*f*(

*x*) = 2

*x*defines a function

*f*that associates any input number with the number twice as large. If

*x*= 5 then

*f*(

*x*) = 10. Two different rules define the same function if they make the same associations, for example

*f*(

*x*) = 3

*x*−

*x*defines the same function as

*f*(

*x*) = 2

*x*.

Thus showing X is dependent on Y.

3. Is function a relation?

Yes it is cause if X changes Y will change as well
