I'm having a hard time understanding this.

Answer 1

Answer:

Hello,

I am not sure if you are still having an issue with this problem but for future reference for you or anyone else the answer is

d. Each vertical line drawn through the graph will intersect a function in only one location.

I thought of it this way:

"Each vertical line" which tells me only one line per "one location" now I could be completely off but this was just my logic and it helped me personally.
