Answer:
The temperature is increasing at the rate of 6.5 degree celcius per second.
Step-by-step explanation:
We are given the following information:
Temperature of a point is given by T(x,y)
After t seconds a bug reaches a point 
At t = 2, x = 2, y = 4
The temperature function satisfies:

We have to find:

Hence, the temperature is increasing at the rate of 6.5 degree celcius per second.
Answer:
A
Step-by-step explanation:
If you were to substitute 2 or -3 into equation A, the denominator would be zero and you would have to divide by zero. Thus there are asymptotes for this function at -3 and 2, matching the graph
