I think the range was >=1 and the domain of f^-1(x) was >= -2.5, right?

Are you sure that the values of k were 63 and -21, not 1/63 & -1/21? :rolleyes:

Hey Guys, I messed up big time in this paper.
Last year when I was in IGCSE someone uploaded a hand-written markscheme after 24hrs had gone, is someone gonna do that here as well? I really wanna have a look. Links?

Oh, I remember that. I was doing IGCSE back then too.
Things like that are rare.

That was easy though! First we had to find the value of m1 by using the formula -a/b. Then you had to find the perpendicular s***, by m1xm2=-1. Then carry it further....

P.S My paper was held past 24 hours
