Best ResponseYou've already chosen the best response.0but this is a 4 mark question and i need the steps to get the mark...... if use calculus i dun think i can get full mark for this question.... (at least 1 mark 1 step)

Best ResponseYou've already chosen the best response.0okay, well that sounds like there's a particular way you're supposed to do it. What class is it?

Best ResponseYou've already chosen the best response.0I'm not sure what you mean by that. Is it an algebra class or something? And does it ask you to complete a series of 4 steps?

Best ResponseYou've already chosen the best response.0i duno which part can be use to find the range :( but i know the syllabus is just in that 2 webpage

Best ResponseYou've already chosen the best response.0I say again, just to clarify... you're looking for the range of the function? Which means all of the possible values it could take? Or you're looking for the remainder of the fraction once you've divided?

Best ResponseYou've already chosen the best response.2lets say, \(\frac {3x^22x1}{x^2+x+2} = k \) => \(3x^22x1 = k(x^2+x+2)\) \((3k)x^2 + (2k)x + (12k) = 0\)

Best ResponseYou've already chosen the best response.2since, x is real, \(b^2  4ac >= 0 \) => \((2+k)^2  4(k3)(1+2k) >= 0\) \((k4)(k+4/7) >= 0\)

Best ResponseYou've already chosen the best response.0I like that! I've never done it that way before. @cwtan I'm somewhat surprised that this is a viable technique for you in this instance given what I read in your syllabus, but I suppose if it works it works.
