Pre-Calculus project involving an alien and his partner struggling with a riddle until they are able to solve it using the help of someone who knew exactly what to do in this situation, using the Vertical Line Test to determine whether a certain figure was a function or not.
The robot hands the aliens a piece of paper with a drawing on it, with a single straight line drawn on it.
``ACCESS DENIED.CODE REQUIRED. CODE HIDDEN IN QUESTION:IS THIS A FUNCTION OR NOT? USE THE VERTICAL LINE TEST.``
"How are we supposed to get this thing working and get to that planet in the distance?!"
"There is an emergency escape pod capable of going there we can use, no?"
"What?! That's a pretty brilliant idea! I should've thought of that from the beginning, good work, partner!"
"Very well then, I shall head off to that planet with the escape pod to ask the lifeforms there for help!"
After using the escape pod to reach Earth, the alien reached a neighbourhood nearby to ask for help...
"Greetings! Urh.. I come in peace..! I only come to ask for help, please help..!"
"Yo, what's up? Oh, you need help with something? Sure, go ahead and ask! But nothing too crazy, alright?"
The Alien hands this boy a piece of paper with a drawing on it in utter confusion.
"Oh, that's easy! Just draw a line from the top of the paper and till the bottom; If there's 1 intersection in that drawing, you got yourself a function! If it's more than 2, then it ain't a function, pal."
"I need to know the answer to this riddle! "Is this a function or not? Use the Vertical Line Test."What even is a vertical line?!"
Full of glee, the alien drew a line and noticed that the drawing on the paper is indeed a function!
"Thank you so much! Now I may further my colonization of the galaxy! Fuhaha! Fuhaha!"
"Anytime, and whatever you say, dude. Nice Halloween costume by the way!... Even though you missed that holiday by a mile, haha!"
