In mathematics the difference between a function and a relation is that each X-value in a function only has a single Y-value.
That means that the functions is made up of different functions - for example, one function for one interval, and another function for a different interval. Such a function is still a legal function - it meets all the requirements of the definition of a "function". However, in the general case, you can't write it as "y = (some expression)", using a single expression at the right.
There are several laws of exponential functions, not just one. Here is just one of them:The derivative of THE exponential function (base e) is the same as the function itself.
For a function of only one variable it mean the derivative with respect to that variable. Thus, f'(x) = df(x)/dx. Occasionally, it can also refer to a variation of a function. For example, a family of functions, f(x), f'(x), f''(x) and so on.
Typically, functions are graphed on x-y coordinates. A function of x means that for every x point, there must be a single y point. You can also many properties by graphing a function, such as the minimum and maximum points, slopes and inflection points, and the inverse of the function (y values plotted on x coordinate, and x values on y coordinate).
There is no single function. In fact there are infinitely many possible functions.

An arcsine is any of the single- or multivalued functions which are inverses of the sine function.

An arctangent is any of several single-valued or multivalued functions which are inverses of the tangent function.
An arccosine is any of several single-valued or multivalued functions which are inverses of the cosine function.

I don't think there is a special name for that. Note that not all functions can be described by a single equation - at least, not in a natural way. For example, a function may be described by parts.
It refers to one.A binary function (binary = 2) takes two numbers as input and gives the result (output) as a single number. Thus, addition is a binary function. Some functions, like squaring or trigonometric functions are examples of unary functions. These have only one input.
1. ios functions returns value while manipulators does not. 2.we can not create own ios functions while we can create our own manipulators. 3.ios functions are single and not possible to be combined while manipulators are possible to be applied in chain. 4.ios function needs <iostream> while manipulators needs <iomanip> 5.ios functions are member functions while manipulators are non-member functions.
