1. The wave heights h in the open sea depends on the speed v of the wind and the length of time t that the wind has been blowing at that speed. Values of the function h = f(v,t) are recorded in feet in T'able 1. (a) What is the value of f (40,15) ? What is its meaning? (b) What is the meaning of the function h = f(30, t) ? Describe the behaviour of the function. (c) What is the meaning of the function h = f(v, 30)? Describe the behaviour of the function.
