AI Thread Summary
The equation f(x+a) = f(x^2+a) requires clarification on the function f and the variable a to determine the value of x. Participants in the discussion highlight the need for more information about the function f to solve the equation effectively. The problem could involve finding a specific function f that satisfies the equation for all x. Without additional details, it's challenging to provide a definitive solution. Understanding the context of the function is crucial for solving the linear equation.

We are studying linear equations in school and the prof gave us this to solve for extra credit:

f(x+a) = f(x^2+a)
what is x?

I don't know what type of equation that is. Can anyone tell me?

Edit: I posted in the wrong section... moving it now.

Depends on what f and a are... are you given the function f? Or are you asked to determine a function f such that the relation you wrote down holds true for every x? Or something completely different?
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
