Hmm so for Q 3 i'm not sure how you mean i did the reverse distributive law wrong... here is my working
On 1st line we get (AUB^c)U(AUB) - De morgans law, second line we use the reverse distributive law
The distributive law says: "A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)"
So we note the A's common in...
For 2009 Test 1A
Q2
i) is it fine to write "f is 1-1 iff for every y an element B, there is at most one x and element of A such that f(x)= y" and " g is 1-1 iff for every y an element of C, there is at most one x an element of B such that f(x)=y"
part ii) i said "suppose g o f(x) = g o f(y)...
im really bad with these Qs so help me out a bit here how did u get the range as [0,1] ?
and for the 2 values u get u go like: x^2(2x+3) then x=0 or x= -3/2 right??
Also how can you prove Q2 2009 Test 1B is invective or subjective ? i think form the graph it does fail the horizontal line test but how would u write out a proof for this one??
Yeah k fair enough, for the one that is false u can just say {{a}} is a sub set of A3 not an element right?
could u also check my answer for 2009 Test 1A Q1 before i add it to the main post
Okay so as we have a topic 1 test this week in our first tute and some of us are still struggling with a few things here and there (including my self) i thought this would be helpful. We can collaborate on answers to past papers and hopefully get any concepts explained to us by each other...
Yeah i would also advise not to drop it just cause you are falling behind a little, you can catch up in a weekend if u are dedicated enough. For the upcoming test this week on topic 1 i am thinking of doing a revision thread(im also sketchy on a few concepts) so that will probs help you out, and...
Well for 1131 only ext.1 is a requirement but for 1141 4u is a requirement i think... so if they have different quizzes for ppl enrolled in 1141 they would be they only ones with 4U questions i imagine.
I was wondering how hard the Assumed Knowledge Quiz test is (plz reply if u have done it and what topic the questions are largely on) and should i spend a day or 2 going over ext1 work to go well in it?
Also what does it mean by "Remember you have 5 attempts and we take the best of them" do...
