precalculus
My book says a way for me to graph/plot points for my function is to write it in exponential form. For example. "Graph (fx)= log base 2(x-2) y=log base 2 (x-2) x-2=2^y x=2^y + 2 So now I can just plug any y value in to get my x value to graph my translated graph. So I was...

When asked to sketch the graph of g(x)= -e^(x+1) +1, how do I turn this equation into exponential form? Or can I? I always get confused on what to do especially when I need to the x part of the equation out of the exponent.

precalculus
My book tells me to solve each exponential equation. I am given a lot of problems such as 6^x+1 = 4^2x-1 where I use In in the problem to help get my answer. However, in the same section, the book starts giving me problems such as 3(2)^x-2 +1=100 and .05(1.15)^x =5 etc. Where ...

precalculus
e^3x-7 x e^-2x =4e First step I get e^1x-7 =4e For the example in my book, the next step they divided by e. But I have no idea how to do this, or what involves?
