heey
can someone please help me clear up a few issues with graphs..
when you draw e to the power of f(x) of say a given function, what do you look for? and also if you are given a graph and told to draw e to the power f(x) what changes and how do you draw it basically...
and i would also appreciate the same guide and help for log f(x)
thanks heaps

i cant be stuffed to draw it. but anyway ways log f(x) is the reflection of e to the power f(x) on the line y=x

y=e^f(x)

1. when f(x) = 0 , y=1
2. y CANNOT be negative, a good way to check if ur graph is correct or not.

y=ln{f(x)}

1.When f(x) = 0, a vertical asymptote exist at the corresponding x value
2. When f(x)=1, y=0
3.f(x) CANNOT be < 0, to draw y, in other words whenever f(x) is <0 ignore dat part.

hi, can someone explain to me what f(|x|) does... and what should i look for.

y=f(|x|) means:

for x>0, y=f(x)
for x<0, y=f(-x)
