A toy rocket was launched from the ground. The function f(x) = -16x2 + 128x shows the height of the rocket f(x), in feet, from t

he ground at time x seconds. What is the axis of symmetry of the graph of f(x) and what does it represent? (3 points)
x = 8; it takes 8 seconds to reach the maximum height and 8 seconds to fall back to the ground

x = 4; it takes 4 seconds to reach the maximum height and 4 seconds to fall back to the ground

x = 8; it takes 8 seconds to reach the maximum height and 16 seconds to fall back to the ground

x = 4, it takes 4 seconds to reach the maximum height and 8 seconds to fall back to the ground
