Question

Is this a function? And is it linear? And why?

Answer 1

Answer:

This is a function, it is not linear

Step-by-step explanation:

You know it's a function when the x values do not repeat like the image above and its not linear because the y values don't a have a pattern.

Answer 2

No it is not a function or linear because it’s not a constant change witch in other words means y: 0->1=+1 than 1->4=+3 it’s not added to the same number
