This is a broad question that depends on the function. Let's look at simple linear ones and you can get some idea. Say f(x)=2x+3
We can write this as y=2x+3.
Now solve for x and we have (y-3)/2=x
so f(y)=(y-3)/2 and this is the inverse function.
We solved for the other variable and wrote the function in terms of it.
So if we have a the point 2 in the original function, f(2)=2x2+3=7
Now f(7) in the inverse gives us (7-3)/2=4/2=2.
For a point (a,b) if f(a)=b, then if g is the inverse g(b)=a.

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 a relation and its inverse relation whenever both relations are functions?
inverse function
What can undo operations?
Inverse functions? (not sure what you mean)
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.
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 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
Is inverse of a function always positive?
No.Some functions have no inverse.
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.
What is a relation and its inverse relation whenever both relations are functions?
inverse function
Inverse supply and demand functions?

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.
What are the inverses of hyperbolic functions?
If f(x)=y, then the inverse function solves for y when x=f(y). You may have to restrict the domain for the inverse function to be a function. Use this concept when finding the inverse of hyperbolic functions.
How do you understand inverse trigonometric formulae?
use the graph of inverse functions,whcih checks the vallues of x and y

What linear functions are non inverse function?
x = constant.
