I'll attempt to answer this. As worded your question makes no sense. All functions are relations, but not all relations are functions. Like all girls are people but not all people are girls.

In relation to what.

A function may be defined over only certain values. That is, it may have only a certain set of values that can serve as input. For example, in elementary mathematics, the principal square root is only defined for non-negative real numbers. This is the "area" over which the function is valid and so it is called the domain. The mathematical term for the set of output values is actually the co-domain, but many people refer to it as the range.

ratios are maths way of say there are eg: 3 boys for 15 so there would be 18 people in the classThe quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

No, there is no relation between the two people.

There is an HUGE number of applications but I'll give you an example: Say you have a function of food consumption (independent variable) against number of people. If you integrate this function you will get a figure for total food consumption.

Harmonic distortion is most simply characterised by an output which is not proportional to the input, but can be derived from the input by some function or other.Outputs which bear no relation to the input are instanced by noise, hum, motor-boating, or crackles, and are not harmonic distortion.Distorted outputs which are related to the input are in practice mostly due to a non-linearity in one or more stages, an overdrive condition, or an unbalanced phase splitting process before a push-pull output stage.Note. people have spent their whole lives on this, and books have been written.

A lot of people think of a function as an "equation," but it can be more general than that. In formal definitions, a function is a "rule" that assigns every input to exactly one output. You might see a function as a graph, an equation, a table, or an obnoxious person that shouts back at you every word you say, but in pig latin. The limit of a function exists if, as the input x approaches something, the output f(x) approaches something--regardless of the output when x actually reaches the thing it approaches. The limit is the thing that f(x) approaches. For example, picture (or Google), the graph of f(x) = 1/x. As x approaches infinity (further and further to the right of the graph), the curve f(x) gets closer and closer to the x-axis--meaning it gets closer and closer to zero.

Real life examples of using zero of a function in math include dividing an amount of money by a certain number of people to find out how much money each person will get when the number is divided equally.
