Hi, I need help with interpreting a figure. You can find it one photobucket. First, type in flutegirl516 in the search bar and then click on the message that says: "Are you looking for the Photobucket user flutegirl516? Click here to see this user's profile"
I have to determine which is 1-1 and/or onto, and why.
f1: A → B, f2: B → C, f3: C →D, and f4: D → E
• Here are the one that I think are 1-1:
f1 and f2
• And here are the ones I think are onto:
f2 and f3
Also it seems f4 is neither, and f2 is both 1-1 and onto.
Am I correct in thinking this or am I completely off and not reading the figure accurately? Thank you for any helpful replies.
