i’m in the 8th grade. My honors classes are sometimes easy but this topic was just difficult. You managed to explain it better than my teacher ever would. Thank you😭

[kryzziadelvalle]

What if the there is one point that doesn’t get anything like there are 3 x values and 4 y values so one gets left out, is that a non function?

[BabyBerryArt]

This is so helpful thank you so so muchh

[luiszavala]

So if there is two same x values and the y is the same let’s say 3 and 3, it’s a function or not?

2:37 but how do u determine the type of function? E.g: one-to-one relation and one-to-many relation. My school needs that

[markanthonyasuncion]

[trinaquimba]

what if two ×-values with same y-value.
