oaktree · Answer

Okay. So first let's tackle is it a function. So do you know how to determine if it's a function?

anonymous · Answer

Heeelp i don't understand

oaktree · Answer

Okay. So if you have two y-values for a single x-value, it isn't a function. So since this one has both -1 and 4 for the x-value 1.2, we know it isn't a function. Get it?

anonymous · Answer
