👉 In mathematics, a function f(x) is equiconvex if and only if f'(x) > 0 for all x in its domain. This means that the derivative of f(x) is positive over its entire domain. In other words, the concavity of f(x) is such that it opens upwards (since the derivative is positive), meaning that the function tends to a maximum as x increases without bound. For example, consider the function f(x) = 2x^
