Hi there!
Your answers to this is the first and third file.
Why?
The functions are increasing because the arrow is pointing upwards.
Let me teach you something I learned in school!
Okay, you know how you read words from left to right? Well, it's the same with math like this! If you see a line on a graph pointing upwards when you look at it from left-to-right, then it's an increasing function. If it's the other way around, it's decreasing.
So your answers, as I said before, are A and C.
Hope this helps! Send me a private message if you need further explanation. :)
