Question

Can you guys tell me if the 6 graphs are functions or not ?

Answer 1

Answer:

in order from left to right : NO, NO, YES, NO, YES, NO

Step-by-step explanation:

here's how you can tell! if any point on the line (or singular point) lines up VERTICALLY with a different point, it automatically is not a true function. thats why a vertical slope is "undefined" because its not a function.

i hope this made sense... have a good day !
