Don’t you think that whoever defined functions as having to pass the vertical line test is kind of stupid?
The whole point of a function needing to pass that test is supposedly because it is said that a single input can not have two outputs. But that’s not true. If x=4, the square root of that could be 2 or -2. The only good reason I could think the square root function uses the absolute value symbol by convention is because people aren’t familiar with the fact that the square root of a number could be plus or minus.

Today is my first tutoring math through zoom for my college. They posted my zoom meeting ID on their website for students to click on to be tutored.
