I already tried working this out before but I was stuck, is it B?

okay since f(x) is the hieght, and it equals 210, 210 is the number of cm

Ok

so then you can guess, that 60 is the number of days which is like you said, it is B

YEAH! Thanks so much, I'm a 7th grader doing 9th grade work so thats why I need so much help haha

This is more of trial and error.

The first one isn't correct

Right? :/

and yes A is 100% not correct

And.... B isn't correct also is it?

Oh ok thanks, I have a few more haha you are really awesome
