What textbook did u get it from

looks like cambridge btw

enrichment of 3B in the ext1 text

Yeah that’s right and then u make the equation greater and equal to 0 I think . Idk if that right but then u just solve for x with the inequality sign

no just greater than, 1/0 isn't valid

enrichment of 3B in the ext1 text

are you a walking cambridge

enrichment of 3B in the ext1 text

So I’ll never be asked this in an adv exam right?

HELPP I CANT DO THESEE AHSHFHFJ

Domain:
Factorise the denominator then solve (root(whatever u got when factorised) > 0)
range:
u need to sketch it or use desmos/geogebra

bc you'd make a good bridging course

Plz Get out

well it's adv content so theoretically u could be asked it
however it's very challenging and it's in the enrichment section, so something like this would only be asked if the examiners are feeling nasty and would likely be split into many parts and be worth a lot of marks

I just realised the question had ‘likewise’ that means u just need to copy ur working out for a (so not much brain power)

1. if u solve the quadratic and identify its concavity u can find the x values where it is negative e.g. if it has x intercepts at x = -2 and 2, and is concave up the quadratic is negative between x = -2 and 2. since u cant square root a negative and cant divide by 0, that gives u the domain (x < -2, x > 2)
2. find the range of the quadratic by finding the y coord of the vertex. e.g. vertex at (1, 3) and concave down = range: y ≤ 3
3. square root that (keeping in mind u can't square root a negative)-> 0 ≤ y ≤ sqrt3
4. find the reciprocal of that (a graph of y = 1/x could be useful) -> y ≥ 1/sqrt3

bro i was gonna do it first

Ok. I’ll prob practice smth like this towards prelim or next year

but that topic falls into the adv section so it's possible (ie not a ext1 topic)

too slow haha
u can still do it and try to explain it better cuz i don't think my answer is very easy to understand

These were the types of questions we did in class bc ‘they’re too easy’

Honestly my teacher thinks enrichment cambridge is fair and if we cant do them we should drop to std (only for adv obviously enrichment ext is diff)

My class never did these sort of ones. Or maybe we did and I just forgot but their not too bad

Its just logic: ‘applying previous knowledge to new concepts’ (quoting my teacher)

definitely don't have a fat prelim and HSC folder
definitely don't have 2 more

HSC '25er infiltrating your GOATED chat as 2025 chat is lacking, and is lowkey making y12 so anticlimactic .
