Suppose you start measuring your height every day, starting today.
You will accumulate a set of pairs consisting of one date and one height.
On one hand there is the set of dates that starts with today and stretches out into the future. On the other hand there is the set of height that you might assume. If you are young then this set might consist only of numbers that are bigger than the one that you record for today. However, if you are fairly old, and becoming a little bit shorter with age, then the numbers in the set might be becoming smaller. In any case the second set will consist only of heights.
The function is the set of pairs that takes one date in the first set and 'maps' it (or connects it) to a height in the second set. The function is the complete set of pairs that you have accumulate thus far.

A real life example of the sine function could be a ferris wheel. People board the ride at the ground (sinusoidal axis) and the highest and lowest heights you reach on the ride would be the amplitudes of the graph.
Functions are an integral part of mathematics, and most students learn them from Algebra II and up. A real life example of a function would be the relation between the height of a ball and how long it has been in the air.
a real life example of an octagon is a stop sign.
electricians use the Square Root function when connecting 3 way outlets with the electral current of an intel processor.

An example of a real life exponential function in electronics is the voltage across a capacitor or inductor when excited through a resistor. Another example is the amplitude as a function of frequency of a signal passing through a filter, when past the -3db point.
A real world example of a cubic function might be the change in volume of a cube or sphere, depending on the change in the dimensions of a side or radius, respectively.
A real life example of the sine function could be a ferris wheel. People board the ride at the ground (sinusoidal axis) and the highest and lowest heights you reach on the ride would be the amplitudes of the graph.
Real life is a real life example!
a roller coaster. It doesnt have a constaant rate of change
a Television is a real life example of a Cube A dice is a real life example of a cube
The current flowing through an electric circuit when you flick the switch on or off.
A real life example for the absolute value function is a football field. Even though the center of the field is labeled zero, you wouldn't say you ran negative feet if you went backwards..
Functions are an integral part of mathematics, and most students learn them from Algebra II and up. A real life example of a function would be the relation between the height of a ball and how long it has been in the air.
An example of a constant function in real life is the speed limit on a particular road, where the speed limit remains the same throughout. Another example could be the price of a particular item at a store which does not change.
