It's probably the best advice.

Look at a question, if it doesn't come to me or I don't have a practical attempt in solving the problem, I skip it within 5-15 seconds to come back to it later.

Really focusing on Q1-6, aiming for above 95% of the questions correct, and Q7-8 I will attempt but not get bogged down If I leave more than half of it blank.

I'm aiming for a 70 :S
What do u need to get for that?
I'd love to get higher maybe 80, but my assessment mark is like 40%

Q3 how do you graph f(x^2) LOL sorry for breaking the thread subject

 

[kr73114]

u sub in values....for example the x intercept is 4, so the x intercept of f(x^2) is +2 and -2. The function f(x^2) will also pass through origin obviously.
You can also sub a random value like 9...when y=9 in original graph, it will become +3 and -3 in f(x^2)
soz if that wasn't clear...its hard to explain

Q3 how do you graph f(x^2) LOL sorry for breaking the thread subject

For x<1 the graph is horizontally expanded, while for x>1 it is squashed
Because x^2 < x (x<1) , x < x^2 (x>1)
