Title: iTute FM Ex 1 CORE Q11
Post by: Dominatorrr on November 03, 2011, 03:22:27 pm

Here's the link if you don't have it already: http://www.itute.com/2011/06/19/free-download-2011-further-mathematics-trial-examination-1/

For Question 11, you can see that from the circle of transformations, 2 transformations exist that can be used to linearise the graph (y versus log x (answer B)) and (y versus 1/x (answer E)), so which one would you use?

Would you have to graph both to see which one linearised it more?

B.
Both can be applied,
But when you apply each, you will see r is higher for option B.

Are you sure, I ended up getting B because I got a greater r for B than E? Also when I graphed both of them, the reciprocal transformation didn't work but the log transformation did?

Lol my bad. I remembered getting the correct answer, and i thought you said E was correct.

Anyway, yeah B is correct because you get a higher r value.
