Answer:

The graph is compressed vertically.

Step-by-step explanation:

The parent function is f(x) = |x|.

Now, some of the solution of this function are

At x = 0, f(x) = 0

At x = 1, f(x) = 1

At x = 2, f(x) = 2

At x = - 1, f(x) = 1

Now, if we replace, f(x) by 3f(x), then we get the equation f(x) = \frac{1}{3} |x|.

Now, the few solutions of the function are  

At x = 0, f(x) = 0

At x = 1, f(x) = \frac{1}{3}

At x = 2, f(x) = \frac{2}{3}

At x = - 1, f(x) = \frac{1}{3}

Therefore, the f(x) values are reduced by the factor \frac{1}{3}.

So, the graph is compressed vertically. (Answer)
