Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4?
nasty-shy [4]
Note that what we want is to compress any point (a, b) in the parent function, to (a, b/4).

(a, b) is a point of the graph of the function f(x)=x^7, thus we can rewrite the point as:
                                     (a, a^7).

This point is compressed to 

                                   \displaystyle{ (a,  \frac{a^7}{4} ).

This means that the function we are looking for is \displaystyle{ t(x)= \frac{x^7}{4}.

Answer: <span>t(x)=1/4x^7
