Question

A toy rocket was launched from the ground. The function f(x) = -16x2 + 192x shows the height of the rocket f(x), in feet, from the ground at time x seconds.

What is the axis of symmetry of the graph of f(x), and what does it represent

Answer 1

What is the axis of symmetry of the graph of f(x), and what does it represent?

x = 12; it takes 12 seconds to reach the maximum height and 12 seconds to fall back to the ground
x = 12; it takes 12 seconds to reach the maximum height and 24 seconds to fall back to the ground
x = 6; it takes 6 seconds to reach the maximum height and 6 seconds to fall back to the ground
x = 6; it takes 6 seconds to reach the maximum height and 3 seconds to fall back to the ground

Answer 2

we can graph this function

Answer 3

i graphed it

Answer 4

its vertex is (6,576)

Answer 5

So its C

Answer 6

my graph is not drawn so well
