hmm im kinda curious...

anonymous · Answer

do you mean f(x)=2 to power x or just f(x)=2x

anonymous · Answer

Explain how to use the graph of f(x) = 2^x to obtain the graph of g(x) = log2x.   sorry about the confusion.!

anonymous · Answer

now I know how to answer your question
first, you need to know the relationship between exponential function and log function. they are the inverse function of each other

anonymous · Answer

for example , the point (1,2) is on the graph of f(x)=2^x, then the point (2,1) will be on the graph of g(x)=log2x. Also, their graphs is symmetric by y=x

Ok thanks, I totally understand what you are saying.
