Yes as they are points lying on f(x) hence satisfy the equation.
do you just enjoy going around being a **** or what?
Could somebody explain (d) for me?
Ah it's because I saw these and was like what haha, it's literally just rearranging but I've never really seen them used so I dunno!
That's what I'm doing, best thing to do in revision for maths.
Domain is the range of x values that you can pit into a function f(x). E,g, if you're function if f(x) = 1/(x-2) then your domain may be x<2.
The range is the range of y values that you get out of your function f(x) and it corresponds to the range. Say if the range for f(x) = 2x + 1 was 2<x<4 then your range would be 5<f(x)<9.
It's a typical 'use the R formula from part (a) and find the min/max', but they've added a few twists. Can you see what the maximum would be?
I have a C3 test on Tuesday. I'm constantly getting a B in C3 so far (58/75). I really want an A in c3 so bad. I'm not sure whether I should do all the solomon papers first and the. The actual past papers or do that the thee way round.
