👉 In mathematics, an upfold is a type of function that has a slope greater than 1. Specifically, it is defined as: $$ f(x) = x^2 - \frac{1}{x} $$ This function grows faster than any linear function for large values of \( x \), indicating its upward behavior. For example, consider the graph of \( f(x) = x^2 - \frac{1}{x} \). As \( x \) increases, the
