Question description

I don't know the steps to solving this problem;

Wind speed typically varies in the first 20 meters above the ground. Close to the ground, wind speed is often less than it is at 20 meters above the ground. For this reason, the National Weather Service usually measures wind speeds at heights between 5 and 10 meters. For a particular day, let the formula f(x) = 1.2ln x +2.3 compute the wind speed in meters per second at a height x meters above the ground for x >= 1.

a. Find the wind speed at a height of 5 meters.

b. Graph f in the window [0,20,5] by [0,7,1] and interpret graph

c. Estimate the height where the wind speed is 5 meters per second.
