Values of the function h = f(v, t) are recorded in feet in the table below.

What is its meaning? According to the table, f(40, 20) = , which means that if a 40-knot wind has been blowing in the open feet. sea for 20 hours, it will create waves with estimated heights of (b) What is the meaning of the function of h = f(40, t)? Describe the behavior of this function. O We fix v and t, resulting in a constant value. 9:23 PM 9/26/2022
