3Paleontologists use the function W(x) = 4 ?2x to estimate the walking speed of a dinosaur, W(x), in feet per second, where x is the length, in feet, of the dinosaur?s leg. The graph of W is shown in the figure. Use this information to solve Exercise

What is the walking speed of a dinosaur whose leg length is 6 feet? Use the function?s equation and express the answer in simplified radical form. Then use the function?s graph to estimate the answer to the nearest foot per second.
