Question

see the graph and justify your answer please.​

Answer 1

Answer:

No it is not a function.

Step-by-step explanation: This is because one x value can only take one y value.

Take any x value on the graph (i.e x=1) and draw a vertical line through it. It cuts the graph at two different y values.

Look at the graph and draw a vertical line through it. If it cuts the graph more than once (in this case twice) it is not a function.
