For a pendulum with length x in meters, the function

$$T ( x ) = 2 \pi \sqrt { \frac { x } { 9.8 } }$$

gives the period of the pendulum in seconds. The period of a pendulum is the time it takes the pendulum to complete one back-and-forth swing. Describe the graph of T as a transformation of

$$f ( x ) = \sqrt { x }$$
