need to find the antiderivative of: ln|x|

I think that it would be just (x) or even (1/2x^1/2),
since ive added to eliminate
natural logs in the past, when both sides where natural logs.... i doubt it though since this is only an expression.

How do you graph y= -2x+3?

I do not know where to start. My professor was getting so mad at us. I went outside and cried. I, in no way understand even the basics. Can someone explain about the pairs I am suppose to have to graph this with. Thank you in advance.

At warm temperatures, air can hold more moisture than it can at cold temperatures. Relative humidity is the amount of vapor the air is holding expressed as a percentage of the amount the air is capable of holding. For example, at 86 degrees Fahrenheit, air can hold a maximum of 30.4 grams of water per cubic meter. If the air at the same temperature is holding only 15.2 grams of water, the relative humidity is 50 percent. At the point at which the air becomes saturated (exceeds the level of water vapor it can hold), it releases water vapor in the form of dew or condensation. If the air at 75 degrees's holding the maximum amount of moisture that it can, and the temperature suddenly drops to 60 degrees, what is likely to be the result?

a) The humidity will remain unchanged.
b) The relative humidity will decrease.
c) Precipitation will be released in the form of rain.
d) Precipitation will be released in the form of hail
e) Precipitation will be released in the form of snow.

I would like everyone to express a moment of epiphany. I beleive that there alot of life's questions out there that have stumped even the most brilliant minds in history that can be answered by an unknown person somewhere. If you have a thought on anything relating to mysteries or scientific paradoxes or any other kind of unsolved delima, let's hear your view on it. What do you think about black holes? or Explain the true nature of gravity and how it works? or Is light a wave or a particle? etc.. etc.. Pick any topic and give us your view. Show us that publicly renoun scientists are not the only smart people out there.... or prove that they are.
