AI Thread Summary
The discussion revolves around the functions defined by f(8) = -23 and f^(-1)(-25) = 3. The first function is denoted as f, while the second is its inverse, f^(-1). There are infinitely many functions that can meet these criteria, so no specific name is assigned to them. The relationship between the function and its inverse is clarified, stating that if f(a) = b, then f^(-1)(b) = a. Ultimately, it concludes that f^(-1)(-23) equals 8.

f(8) = -23 and f^(-1)(-25) = 3

what is this functions called??

What is the functions called? I'm not sure I understand your question. The first function is called f, and the second function is called the inverse of f.

There are infinitely many functions that satisfy the conditions f(8) = -23 and f^(-1)(-25) = 3, so there is no special name for such functions.
 


so, the question states that

the inverse of f (-23)= ?

What's the question tells me to find anyway??
 


About this, i finally found a webpage that would allowed me to understand inverse function. thanks anyway.
 


Yes, if f(a)= b, then f-1[b)= a, by the definition of "inverse". If f(8)= -23, then f-1(-23)= 8.
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
