**tonya**, Thursday, February 12, 2009 at 8:45amfind the vertical asymptotes, if any, of the graph of the rational function

f(x)=x/x(2)+8

**tonya**, Thursday, February 12, 2009 at 9:22amWhen the temperature stays the same, the volume of a gas is inversely proportional to the pressure of the gas. If a balloon is filled with 87 cubic inches of a gas at a pressure of 14 pounds per square inch, find the new pressure of the gas if the volume is decreased to 29 cubic inches.

**drwls**, Thursday, February 12, 2009 at 10:01amPressure times Volume is constant in a costant-temperature situation. Let the new pressure be P.

P * 29 = 14 * 87

P = (87/29)*14

Do the calculation.

I am going to guess you mean

f(x)=x/(x^2+8)

( the ^ sign is the standard way to indicate an exponent)

Vertical asymptotes result when a division close to zero takes place, so

you are looking at the x2 + 8 part.

but this cannot have a real solution.

since we would have to solve x^2 = -8

so your function has no vertical asymptotes.
