Really? And here I am hoping it'll not be too hard. I hope that it's at least doable in the time given,...
Ahh, it'll be alright. The one thing I learned from last year was: check your work. I made a few silly mistakes in C4 that could have easily secured 100UMS and I wouldn't be in this position. Also... simplify! Before anything!!!!
Well if you want to be like that then what's the least easy? All the ones I've done basically ask the same thing over and over again. Surely there's at least 1 paper with a surprise dodgy question? I'd rather encounter something new now rather than tomorrow
guys just 1 quick question... is domain the x values and range the y values?
Pretty much, though I would add that it is what values you can/can't put in for the x values and what values you can/can't get out.
For example, with 3/x, you will never be able to put in x = 0, so the domain is x in the reals, excluding 0. With e^x, you can put in any x value but you will never get out a negative value or 0 (e^x = 0 can't be solved). With lnx, you can't put in any negative values of x, or 0. so the domain is x>0.
