8) A blender's rotation rate slows down the more liquid that is added to it. From empty, it goes at around 1,275 rotations per second. The slowdown rate is three rotations per second less than four times the liquid's square height (represented as h). Which of the following equations best represents the appliance's rotation rate B(h)? 

1. 3-4h²
2. 1,275-(4-12h)
3. 1,275-(12h-3)
4. 1,275-(4h²-3)
