The equation p= 14.7e^(-0.21x) gives the average atmospheric pressure, in pounds per square inch, at an altitude x in miles above sea level. What is the atmospheric pressure at an altitude of 2 miles? Round your answer to the nearest tenth.

Note: The e is raised to the (-0.21x)

Okay so what I did was I put the 2 in place of the x and since I didn't know what else to do , I put it all into mu scientific calculator and got this answer,
120.73 pounds per sq. in.

I need to find out what the process is to solving it because the instructor didn't give us any examples and I need to know for my final exam.
Any help would be greatly appreciated.

And another thing, how could there have been a Big Bang?

First of all, there were no ears, thus no one would've heard anything. Secondly, if there was nothing, how could the universe have started expanding into nothingness. There would have been nothing for the sound waves to have expanded into
