A drone's vertical displacement (in meters) over time is modelled by

D(x) = x^4 - 3x^3 + 3x + 3

, where

x

is time in seconds. A wind gust's force variation is modelled by

F(x) = x^2 + x - 4

. An engineer models a control response line

R(x)

that passes through the point

(1, F(1))

and has a slope of

-2

. Compute the total response

D(x) + R(x) \cdot F(x)

. Choose the correct option.
