Hmm.........the answers I obtained were :
i) 0 < K < 4
ii) You need to replace k = 4 in both equations and then solve them simultaneously to obtain the coordinates of the point of intersection
beautiful
same here lol though a lot of people i asked told me they simply got k=4. it had to be 0 < K < 4 instead right? my coordinates were (0.5, 2)
anyways for the rate of change question, were we just meant to plug in 5 to our differentiated equation?
for the functions question, what did u guys get for the range of g(x) and the domain of g^-1(x)?? i think i got >3 for the range and <3 for the domain. Was it just > or was it >=? ...and also how did u calculate h(x)?
for the last question, I only managed to find the volume under the line AB due to time issues. How many marks do u think i would get out of 9 for that?
