Euploidy is the condition of having a complete set of chromosomes, which is essential for normal development and functioning. Aneuploidy, on the other hand, involves the presence of an abnormal number of chromosomes, which can lead to various genetic disorders and developmental issues.
Given, the function \( f(x) = \frac{a^x + a^{-x}}{2} \) (\( a > 2 \)), then \( f(x+y) + f(x-y) \) is equal to
