Homework Help: How to graph a function by transforming a graph of a function form?

  1. Jun 30, 2010 #1
    1. The problem statement, all variables and given/known data
    Sketch the graph of the function y=(x-3)^2 by transforming the graph of an appropriate function of the form y=x^n

    2. Relevant equations

    y=(x-3)^2, y=x^n

    3. The attempt at a solution
    Precisely speaking, im just totally confused with what the question is asking. i mean i know how to graph y=(x-3)^2 bit idk what the y=x^n is about. thanks so much!

    They asked you how to transform graph of y=x^2 function to graph of y=(x-3)^2 function.

    They want you to start up with graph of y=x^2 and get y=(x-3)^2, which is just shifted in x axis.

    but it says y=x^n so how did u get x^2? not to sound whiny, just confused?

    You have to choose the value of n. In order to get the given function from y=x^n, the value of n has to be taken as 2.
