Answer:
117
Step-by-step explanation:
Answer:
answer it s 12. just put the value
Because the boat travels the distance twice as fast when going 3 three miles/hour faster the original speed must be 3 miles/hour. so the distance upstream would be 21 miles/hour.
The function that is growing at the fastest rate is p(x) = 12x^3 + 9.
This is a cubic function, meaning that x is raised to the third power. This is the only function that is raised to the third power, so it will increase the fastest.
