Yes I have been "dead" for a while, I am back! I was learning about logarithms and on the test it threw this equation at me.

\(y=-\ln x +2\)

What on earth is LN? Or is it 1n? Why didn't my book tell me about this?

On a side note, what is the proper way to pronounce logarithm?

Not sure what you are asking, but:

-y = -ln x + 2

2+y = ln x

e^(2+y) = e^(ln x)

e^(2+y) = x

I've never heard it pronounced any other way than log rhymes with 'bog' 'dog' 'hog' 'cog' 'fog' etc......

This is not an equation.....it's a graph of the natural log function reflected about the x axis and shifted up 2 units

Here's a graph of the parent function and this one :
