Posted: Mon Sep 29, 2014 2:49 am
Can some explaine the Q27 from GRE9367?
I select B, but the correct answer is A.
I do not know why f(y) should be f(y)^2.
sorry, I can not write the Q here, because I do not have Latex:(
Thanks
.............................................................................................................
about Q 37 also I have problem,
I chose A as answer, because the first row product in 3 , then det =9*3=27 and after that the third row product in -4, then det=27*(-4)=-108,
but answer is -27. I do not know why:( can someone explain that?
