i realize there is a similar thread here But the questions are not the same.(adsbygoogle = window.adsbygoogle || []).push({});

1.)Function is a relation but i don't know what relation exactly means. Its supposed to be a condition associating two objects but also takes in the quantitative factor in maths?

2.)Anyways, functions can be defined as equations but not all of them are expressed as equations.

Can someone give me an example and state why?

3.)When one associates an element with another element, it doesn't necessarily imply equality but functions are defined as F(x) = y, where x and y are the respective elements . Doesn't this become an equation even though x and y itself are not similar things.

####But then again when the elements are numbers, i see that the function(condition) f itself becomes equal to y

e.g. :- let f be the condition where every value of x from R subtracted by 2. then y= x-2. I thought y and x were related by f but here y = f(x)####
