Q6.A drone's vertical displacement (in meters) over time is modelled by D(x)=x4−3x3+3x+3, where x is time in seconds. A wind gust's force variation is modelled by F(x)=x2+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)⋅F(x). Choose the correct option.
