SUMMARY
This discussion focuses on counterexamples to disprove specific mathematical statements regarding real-valued functions. The participants confirm that a real-valued odd function can be strictly monotonic, using the hyperbolic sine function, sinh(x), as an example. They also explore the concept that a periodic function can be transformed through phase shifts to no longer be classified as odd or even. Additionally, they discuss that a real-valued monotonic function can indeed be even, exemplified by the constant function f(x) = 2.
