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 cubic function can be used to represent the volume of a 3-dimensional object, or can be used to model a position of a certain unit.

For someone packing whole house the cubic function is important to factor the amount of storage needed to move a home. Another real application would be in manufacturing and filling a box with product.
There are no real life applications of reciprocal functions
They are both polynomial functions. A quadratic is of order 2 while a cubic is of order 3. A cubic MUST have a real root, a quadratic need not.

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 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.
Every real number is a cubic number: it is the cube of its cube root!
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.
