باختصار ، الصورة المسبقة للدالة هي المكان الذي تبدأ فيه ، والصورة هي المكان الذي تنتهي فيه. إنها مجرد أسماء معقدة للغاية لعملية أساسية للغاية (أتمنى أن يشرح المعلمون هذا بشكل أفضل ولكن لا يبدو أنهم يفعلون ذلك) The above was translated from my English response: in short, the pre-image of a function is where it starts, the image is where it ends. They are just over-complicated names for a very basic process (I wish teachers explained this better but they don't seem to)
Any other similar questions, check out the channel for more here www.youtube.com/@latedeveloper7836/videos or just ask in the comments! Best of luck!
Straight to the point, thank you!
happy to help
Awesome video! Would 3 also be the pre-imege of C since 1 and 3 both point to C?
yes, I believe so

Great simple example. Thx

Damn! You made it easy!!😁
It really is - just so many people like to make things so complicated, I had to make this video!
Awesome! Thank you! Do you know why they call it an image?
Good question! Unfortunately, I do not! It's an odd name for it, for sure
Thanks!
Thanks a lot

هل يمكنك تغيير التسميات التوضيحية المغلقة إلى اللغة العربية واتباع هذه الطريقة؟ آمل أن تكون هذه الترجمة منطقية! حظ سعيد
