What is the meaning of the function W = f(-15, v)? Describe the behavior of this function. The function W = f(-15, v) means that we fix T at and allow v to vary, resulting in a function of one variable. In other words, the function gives wind-chill index values for different wind speeds when the temperature is °C. From the table (look at the row corresponding to T = -15), the function ---Select--- and appears to approach a constant value as v increases. What is the meaning of the function W = f(T, 80)? Describe the behavior of this function. The function W = f(T, 80) means that we fix v at and allow T to vary, again giving a function of one variable. In other words, the function gives wind-chill index values for different temperatures when the wind speed is km/h. From the table (look at the column corresponding to v = 80), the function ---Select--- almost linearly as T increases.

Suppose that Nolan throws a baseball to Ryan and that the baseball leaves Nolan's hand at the same height at which it is caught by Ryan. If we ignore air resistance, the horizontal range r of the baseball is a function of the initial speed v of the ball when it leaves Nolan's hand and the angle 0 above the horizontal at which it is thrown.
