hi, i'm basically a bit confused as to how to solve this vector question, in other words, in what i have to do which is confusing me...(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

This is a sketch of the curve with equationy = f(x)

It passes through the origin O.

(the sketch has no value on or anything, its simply a happy parabola then passes through the origin on the left side a bit of the way up, and dips in the negative y values)

The only vertex of the curve is atA (2, -4)

a) Write down the coordinates of the vertex of the curve with the equation (boldare my answers)

i) y = f(x-3)(5, -4)

ii) y = f(x) -5(2, -9)

iii) y = -f(x)(2, 4)

iv) y = f(2x)(1, -4)

The curve with equationy=x^2has been translated to give the curvey=f(x)[/]

b) findf(x)in terms ofx

2. Relevant equations

(I dunno if the first half of the question is needed, if it is, say so and ill post it up)

3. The attempt at a solution

not really sure, i know how functions work, I know all about vectors too, but not sure what it means by "translated", and how i would find out the answer.

my instinct says the answer is simplyx^2, but somehow I dont think it is, and i certainly dont think that is worthy of 4 marks :S

hope you can help, thnx

i added in the entirity of the question now..
