input
Logarithms and exponential functions are inverses because they effectively "undo" each other. An exponential function, such as (y = b^x), transforms an input (x) into an output (y), while the logarithm, (x = \log_b(y)), takes that output (y) and returns the original input (x). This relationship can be expressed mathematically: if (y = b^x), then (x = \log_b(y)), confirming that one function reverses the effect of the other. Thus, they are defined as inverse operations in mathematics.
Functions and Expressions are representations of relationships that exist among entities, however a function always returns a value (or result)
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
The inverse of a function is its reflection in the line y=x. so the only function that returns its own inverse is the line y=x or any part of the line y=x
The identity function is a mathematical function that always returns the same value as its input. In formal terms, for any input ( x ), the identity function is defined as ( f(x) = x ). It serves as a fundamental concept in various fields, including algebra and calculus, and is used to illustrate the properties of functions and transformations. Essentially, it acts as a "do nothing" function, leaving its input unchanged.
output
A __________ function takes the exponential function's output and returns the exponential function's input.

The PPMT function returns the amt. of interest in a specified instalment number whereas the PMT function returns the amt. of interest in every EMI payment.

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.
char SomeFunction();This has nothing to do with menu functions. It is a straight C/C++ answer. Menu functions depend on the platform API, not on C/C++.
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.
