A typical formula for exponential decay is y(t) = c*exp(-r*t) , where r > 0. The domain is all reals, and the range is all positive reals, since a positive-base exponential always returns a positive value.

The minimum function is the function that takes two arguments and returns the smallest of the two. Alternatively the function can take any finite amount of arguments and return the smallest.

The coalesce function returns the first expression that contains the highest in data precedence. If all other expressions are considered 'nonnullable, then the result will be labelled nonnullable as well.

In the C Programming Language, the fabs function returns the absolute value of a floating-point number

The domain is the set of values that x may take that gives back an answer that makes sense. The range is the set of values that are possible results of the function. the "log" function does not accept 0 or negative values on its domain and returns negative, zero and positive numbers (ie all real values). The next function does not appear properly but you could figure it out

Yes, it does return. There are only few functions that do not return, like exit, exec, longjmp.

Excel has a category called Logical Functions. The IF function is the one of those that most people use and associate with returning True or False values. Other functions also return True or False values. There is a TRUE function and a FALSE function. The OR function and the AND function can be used to return True or False values too. The NOT function can reverse a True or False value, so it also returns True or False.

A constant function returns the same value for all inputs but that value may differ from the input. Examples: x*c = y (where c is a constant) x+0 = y The identity function returns the same value as the input for all inputs. Examples: x+0 = y x*1 = y

A function. However, not all languages differentiate between procedures and functions. In C and C++ for instance, a function that returns void is (technically) a procedure but it is still regarded as being a function even though it does not return a value. Also, in C++, constructors, destructors and type conversion operators don't have a return type of any kind (including void) but are not regarded as being either procedures or functions.

Functions return a value.NoteThere are no procedures in C, only functions with no return value (type void is used to indicate that). In general a function is the purpose or what a system actually does( what output it returns) and a procedure is how that output is returned.

The return statement is used in functions to return control to the caller. If the function is declared non-void, the return statement also allows the programmer to return a value to the caller.
