If f(x) = 2 3 x + 9, find f−1(x). A) f−1(x) = 3x − 9 B) f−1(x) = 2 3 x + 9 C) f−1(x) = 3 2 x + 27 2 D) f−1(x) = 3 2 x − 27 2

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m
