<h2>Answer:</h2>

The following which represents the graph becoming more narrow is:

                    B.    kf(x)

<h2>Step-by-step explanation:</h2>

We are given a parent function f(x) as:

          f(x)=x^2

and k=3

Now, we know that the transformation of the type:

          f(x)+k

shifts the graph of the function k units upward while there is no change in the shape of graph.

Similarly the transformation f(x+k) and f(x-k) shifts the graph of the original function k units to the left and  k units to the right but odes not change the shape of the function.

            Hence, the answer is:

                      B.    kf(x)

   Since, the  transformation is a vertical compression and the graph becomes more narrow.
