1. The problem is to create a function on Desmos without solving the problem manually. 2. Desmos allows you to input any function directly to visualize it. 3. Since no specific function was given, we cannot provide a specific formula. 4. To use Desmos, simply enter the function in the form $y=...$ in the input box. 5. Desmos will automatically show intercepts and extrema if the features are enabled. 6. This approach does not require manual solving but only inputting the function.
