The derivative of f(x) = 4 x3 - 5 x2 + 7 x - 9 with respect to x is:
f'(x) = 12 x2 - 10 x + 7
f'(x) = 12 x2 - 10 x
f'(x) = 4 x2 - 5 x + 7
f'(x) = 12 x3 - 10 x2 + 7

The density of an ideal gas at temperature T and pressure P is rho. If the pressure is tripled and the absolute temperature is halved, the new density becomes:
3 rho
1.5 rho
6 rho (since rho is proportional to P / T)
0.67 rho
