Answer:
4. 2. 2. 4. 5. 5. 10. 15.
Step-by-step explanation:
x−1 x+1. = ∞. 2. All the vertical asymptotes of the function f(x) = x2 − 1 x3 − 9x are at. Answer: x = 0 and x = ±3. Solution: Write f(x) = g(x) h(x) ... x→a− f(x) or lim x→a+ f(x) is ±∞. For a = 0, lim x→0+ f(x)=+∞. For a = 3, lim x→3+ f(x)=+∞. ... 5. 10. Which of the following gives the graph of f (x)
Answer:
The correct option is D) 
Step-by-step explanation:
Consider the provided information.
People are entering a building at a rate modeled by f (t) people per hour and exiting the building at a rate modeled by g (t) people per hour,
The change of number of people in building is:

Where f(t) is people entering in building and g(t) is exiting from the building.
It is given that "The functions f and g are non negative and differentiable for all times t."
We need to find the the rate of change of the number of people in the building.
Differentiate the above function with respect to time:
![h'(x)=\frac{d}{dt}[f(t)-g(t)]](https://tex.z-dn.net/?f=h%27%28x%29%3D%5Cfrac%7Bd%7D%7Bdt%7D%5Bf%28t%29-g%28t%29%5D)

It is given that the rate of change of the number of people in the building is increasing at time t.
That means 
Therefore, 
Hence, the correct option is D)
