    Graphing Functions...

    I am trying to understand Quadratics Functions but I got lost whilst working on the homework....


    I am asked to graph the function f by starting with the of y=x^2 and using transformation.....


    Ok I am asked to solve this;

     f(x)=\frac{1}{4}x^2

    My question is this, if x equals 1, then is 1 added to the 1/4 or multiplied to the 1/4?

    Thank you all!

    I'm not entirely sure I understand your question. Judging by the equation given, it's multiplied. The graph for f(x)= \frac{1}{4}x^2 will look like a squashed version of f(x)=x^2. That is, it'll be compressed by a factor of four.

    ok so then if x=1 then the function would like this...?!

    F(1)=\frac{1}{4}(1)^2 Ok. then knowing that (1)^2 = 1 then does the function look like this?

    F(1)=\frac{1}{4}1 or  F(1)=\frac{1}{4}(1)

    thanks
