The distance between two functions f(x) and g(x) is maximal when the functions are completely different from each other. In other words, when the functions have the largest possible difference in their values at every point in their domain. This could occur when the two functions have completely different shapes, or when one function has much larger or smaller values than the other function across their entire domain. **

The result is only fx 15x. When multiplying a variable by a constant, the result is simply the variable followed by the product of the constant and the variable. In this case, the result is fx 15x, not fx 15x15. **

The decision between Forex trading and crypto trading ultimately depends on individual preferences, risk tolerance, and investment goals. Forex trading involves trading fiat currencies in the foreign exchange market, which is the largest and most liquid market in the world. On the other hand, crypto trading involves buying and selling digital currencies like Bitcoin and Ethereum in the cryptocurrency market, which is known for its high volatility and potential for significant gains. Both markets offer opportunities for profit, but they also come with their own risks and challenges. It is important to thoroughly research and understand both markets before deciding which one is better suited to your investment strategy. **

To determine the functions f(x) and f'(x), one can use various methods such as differentiation, integration, and numerical methods. Differentiation can be used to find the derivative of a function, which gives the slope of the function at any given point. Integration can be used to find the original function from its derivative. Numerical methods, such as finite difference methods or Taylor series, can also be used to approximate the values of f(x) and f'(x) at specific points. Additionally, graphical methods, such as plotting the function and its derivative, can provide insight into the behavior of the functions. **

The Casio fx 991ES, fx 991DE X, and fx 991DE Plus calculators are all part of the fx-991 series but have some key differences. The fx 991ES is the basic model with features like natural textbook display and 417 functions. The fx 991DE X is an advanced version with additional features like spreadsheet calculations and QR code generation. The fx 991DE Plus is similar to the fx 991DE X but lacks some of the advanced functionalities like spreadsheet calculations. **

The Casio fx 991ES, fx 991DE X, and fx 991DE Plus are all scientific calculators with similar functionalities. However, the fx 991DE X and fx 991DE Plus models have additional features like QR code generation, spreadsheet calculations, and improved display resolution compared to the fx 991ES. The fx 991DE X also has a larger memory capacity and faster processor speed compared to the other two models. Overall, the fx 991DE X and fx 991DE Plus offer more advanced capabilities compared to the fx 991ES. **
