👉 In mathematics, an implicitly defined function is a mathematical expression that requires the substitution of one or more variables in order to calculate its value. This means that instead of defining the entire function explicitly, we can only use it if certain conditions are met. For example, consider the following equation: ``` f(x) = 5x - x^2 ``` This equation defines a function f(x) whose value depends on x and has an explicit form. However, since f(x) is
