The zeros of a parabola are 6 and −5. if (-1, 3) is a point on the graph, which equation can be solved to find the value of a in the equation of the parabola?
a.3 = a(−1 + 6)(−1 − 5)
b.3 = a(−1 − 6)(−1 + 5)
c.−1 = a(3 + 6)(3 − 5)
d.−1 = a(3 − 6)(3 + 5)

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.
