[x-3] [x+4]

Step-by-step explanation:

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f (x )equalsStartFraction x

Answer:

The rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities are:

a) 0.52

b) 2.63

Step-by-step explanation:

The rate of change of a function at a given point P can be obtained by evaluating the 1st derivative of the function in P. Thus,

$f(x)=\frac{x^2}{2(1-x)}$

$\frac{df(x)}{dx} = \frac{d(\frac{x^2}{2(1-x)})}{dx} \\\frac{df(x)}{dx} =\frac{x}{1-x} + \frac{x^2}{2(1-x)^2} \\\frac{df(x)}{dx} = -\frac{x(x-2)}{2(x-1)^2}$
