I'm currently reviewing for a Calculas exam I have soon, and although there are a few review questions I can't seem to get, I'll stick with this one. (By the way, if it is super simple, excuse me, I really CANT do calculas.)
Question: Determine the equation of the line perpindicular to f(x)=1/2e^x+1 at its y-intercept.
What I did was found the dervitive, which I got to be the same thing (f'(x)=1/2e^x+1) although it could be wrong. Only problem is that I have no clue what to do after that. The answer is suppose to be y=e/2 x+e/2
Any help is appreciated!
