Two functions are the inverse of one another if, for any value "x" (within the relevant range of numbers), if you apply the first function, and then you apply the other function to the result, you get the original value ("x") back. For example, starting with 3, if you square it you get 9; if you take the square root of 9, you get 3. The same happens for any non-negative number; thus, squaring and taking the square root are inverses of one another.

What are the two types of inverse functions?
These are the for inverse operations:Multiplications inverse is divisionDivisions inverse is multiplicationAdditions inverse is subtractionSubtractions inverse is addition
What is the relationships between inverse functions?
The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain. The domain of a function is the range of the inverse function. The range of a function is the domain of the inverse function.
Is inverse of a function always positive?
No.Some functions have no inverse.
How are exponential and log functions related?
One is the inverse of the other, just like the arc-sine is the inverse of the sine, or division is the inverse of multiplication.
How is integer subtraction related to integer addition?
they are inverse functions

Why inverse is called Circular function?
An inverse is NOT called a circular function. Only inverse functions that are circular functions are called circular functions for obvious reasons.
What is an inverse function in mathematics?
Inverse functions are two functions that "undo" each other. Formally stated, f(x) and g(x) are inverses if f(g(x)) = x. Multiplication and division are examples of two functions that are inverses of each other.
What does the word inverse mean in math terms?
Mathematically, an inverse is an opposite, it is something that reverses what its inverse does, for example, addition and subtraction are inverse functions, as are multiplication and division. The inverse of a fraction is obtained by exchanging numerator and denominator; the inverse of a half is two.
Is inverse of a function always positive?
No.Some functions have no inverse.
Which functions do not have an inverse?
y = x2 where the domain is the set of real numbers does not have an inverse, because the square root function is a one-two-two mapping (except at 0). Any polynomial with more than one root, over the reals, has no inverse. y = 1/x has no inverse across 0. But it is possible to define the domain so that each of these functions has an inverse. For example y = x2 where x is non-negative has the square root function as its inverse.
How can you tell if functions are inverse functions?
If two functions are the inverse of each other, they reverse or undo what the other function does. To give the simplest example, addition and subtraction are inverse functions, so that if you start with 7 and add 3 you get 10, and then if you subtract 3 you are back to 7, which is what you started with, so the subtraction reverses the effect of the addtion (if you subtract the same amount, which in this example was 3).
What is a relation and its inverse relation whenever both relations are functions?

What is the answer of opposite or inverse?
Two operators are opposites or inverses if their combined mapping is the identity mapping. Less technically, one mapping must reverse the effect of the other. There are problems, though, when dealing with even fairly common functions. Squaring is a function from the real numbers to the non-negative real numbers, but there is not a single inverse operation. [+sqrt and -sqrt are the two inverse functions over the range.]
