# Where what how functions

functions are mathematical entities that assign unique outputs to given inputs sounds simple think again in this topic you will evaluate graph analyze and create various types of functions.

Algebraic functions are a way to express a certain equation in term of input and output for example a simple function might return twice the.

A multivariate function or function of several variables is a function that depends on several arguments such functions are commonly encountered such functions are commonly encountered for example the position of a car on a road is a function of the time and its speed.

One common use for the and function is to expand the usefulness of other functions that perform logical tests for example the if function performs a logical test and then returns one value if the test evaluates to true and another value if the test evaluates to false.

The if function can perform a logical test and return one value for a true result and another for a false result for example to quotpassquot scores above 70 ifa1gt70quotpassquotquotfailquot more than one condition can be tested by nesting if functions the if function can be combined with logical functions.

Function parameters are listed inside the parentheses in the function definition function arguments are the values received by the function when it is invoked inside the function the arguments the parameters behave as local variables.

functions segmenting code into functions allows a programmer to create modular pieces of code that perform a defined task and then return to the area of code from which the function was quotcalledquot the typical case for creating a function is when one needs to perform the same action multiple times in a program.
