t=2 ⇒x=6 (dy/dx) = 3x^2 −4x ]_(x= 6) = 3(36)−24 = 108−24 =84

$$\mathrm{t}=\mathrm{2}\:\Rightarrow\mathrm{x}=\mathrm{6} \\ $$$$\left.\frac{\mathrm{dy}}{\mathrm{dx}}\:=\:\mathrm{3x}^{\mathrm{2}} −\mathrm{4x}\:\right]_{\mathrm{x}=\:\mathrm{6}} \\ $$$$=\:\mathrm{3}\left(\mathrm{36}\right)−\mathrm{24}\:=\:\mathrm{108}−\mathrm{24} \\ $$$$=\mathrm{84} \\ $$
