Methods 2009 Exam 1 Suggested Solutions

If they do not specify 'in simplest form', you can leave it as it was.

Also just a quick question, contrary to what I wrote above () I did simplify my answer for 1b,to 1/2(pi+1)^2. Is this still correct?

I read the instructions 10 times.

Lose 1 for answer mark I reckon.

Awesome
I think that puts me at 38, highly doubt my explanation for 10B was sufficient :|

I wrote like, two different things, but I think I was too vague.
Should have done a graph like TrueTears.
Silly.

yo, for the inverse function question, a hyperbola is a fuction anyways and since they didnt ask for a domain, you wouldnt lose marks would you? If you look at the 06 exam, it asks to find the rule and then an alternative part asks to find the domain - so will i lose a mark?

I had no idea about 10b), I waffled on about rounded values. :S

Yes you'd definitely lose a mark if you didn't state domain.

A function is defined by the rule AND domain, since the question asked for the FUNCTION, a domain and rule must be given.

this was a joke of an exam... it didnt seperate the better students from the 'not so good' students... even though that sounds bad every1 is gonna get the same mark.

But function notation wasn't specifically required right?
It's okay if you just wrote down the domain and the rule separately?

Yeah I said that in the solutions, "...Note function notation is not necessary but a rule and domain must be given..."

[avram_grant]

if you look at the 06 exam, the first part says find the rule, and the examiners report doesnt state the domain

Despite being an easy exam, lots of people have stuffed up !

Personally I dropped 2 marks according to TT solutions.

Yeah... the question asked for the rule...

Whereas this one asks for the function.
