Sketch the graph of a function f(x) that satisfies all the given conditions. Clearly label any asymptotes, extreme values and points of inflection.
f(x) is only discontinuous at x = −4.
f(x) has a global minimum but no global maximum.
f'(x) > 0 only on the intervals (−∞, −4) and (1, 3).
f(x) only changes concavity at x = −1 and x = 4.
limx→∞ f(x) = 4.

In words, but making use of equations where appropriate, explain how the Principal of Conservation of Linear Momentum is a demonstration of Newton’s third law of motion. In particular, consider a simple collision between two objects. The collision may be either elastic or inelastic. It may be head-on or oblique. State how the changes in motion as a result of this collision relate to Newton’s Third Law. Finally expand your reasoning to cover a many particle system.

Draw 1000 samples of size 10, 25, 40 from exponential distribution with mean 10 and threshold 0 and calculate mean for each sample. Now produce histogram for sample mean.
a. What do you notice in the shape of the distribution of sample mean as sample size increases? Also, what changes in the standard error of the sample mean?
b. As the sample size increases , the sample mean goes to what number?

What are futures contracts? Give an example of how a futures contract can be used as protection against commodity price changes. Why did the price of the May WTI futures contract fall to about -$40. Is there a surplus of oil? What does this have to do with the state of the economy? Explain.
Note: Each WTI contract is for 1000 barrels of oil, and each barrel contains 42 gallons.

How would an organism be able to survive these conditions on another planet? Please explain.
Thermodynamics - the temperature is around 233.15 K (-40 F)
Acquiring energy - receives about 70% of the sunlight that Earth receives from the Sun
Gravity - increase of gravity of 30% compared to Earth. However,more gravity means greenhouse effects increase the overall heat of the planet.
Circular orbit - seasonal changes in climate would be minimal.
