Robert is a stuntman planning to jump off a bicycle ramp and over an array of trucks. He identified a few quantitative relationships and modeled them: Function | Input | Output - | - | - $S$| Height of the ramp, $r$ | Speed at the edge of the ramp, $S(r)$ $D$ | Speed at the edge of the ramp, $k$ | Distance of the jump, $D(k)$ $T$ | Distance of the jump, $x$ | Number of trucks Robert can jump over, $T(x)$ **Which of the following represents the distance of Robert's jump as a function of the height of the ramp?** [[☃ radio 1]]
