The question says sketch the curve: y=x^3-6x^2+9x

I drew it with solutions 0 and 3,3.

The next question asks:

Using your answer to (b) (the last question) sketch on a separate diagram the curve with equation: y=(x-2)^3-6(x-2)^2+9(x-2) showing the coordinates of the points at which the curve meets the x axis. I don't know where to begin or what the answer has to do with the previous question.

I drew it with solutions 0 and 3,3.

Have you done Graph Transformations?

You have drawn f(x) and now need to draw f(x-2)

Have you done Graph Transformations?

You do notice the similarity don't you?

So it's the same graph but just 2 units to the right? Would you get the same answer from expanding because that's what I began doing.

But you would be wasting time

How would I find the equations of the asymptotes of y=3/x+2

What do you know about asymptotes?

its a line that is approached but not touched by the curve

Lol, this was made when I was in year 11, I'm doing AS

So - do you know what value x cannot take?

Now you need the y asymptote

Can you see a value that y cannot =

So you know one asymptote x=-2

Now you need the y asymptote

Can you see a value that y cannot =

Does it have to be a whole number? Is there a way to calculate it?

Simply spotting in this case

Splitting the numerator

Dividing by x

There are a number of ways - have you been shown any

I haven't really learned about this. I was shown the spotting one. Which is the short/easiest?My exam board is edexcel if there's a specific one I must know

Clearly "spotting" is the shortest - so if you have been shown that use that
