Thanks! Jun 5 comment Finding the Derivative Of $f(x) = 7\ln(5xe^{-x})$ I see. This is what DonAntonio said. You crystalized it for me. Thanks! Jun 5 asked Finding the Derivative Of $f(x) = 7\ln(5xe^{-x})$ Jun 5 comment Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? Ahh. It must have been the factoring that messed me up. I didn't factor the numerator. I haven't factored that kind of poly in such a long time. Thanks the the help! Jun 5 comment Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? The way you split up the function helps a lot. In the second explanation I have no idea what you did. I'd look into it deeper if I had more time. Thank you! Jun 5 accepted Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? Jun 5 comment Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? Thats exactly how I worked it out originally. I just missed something along the way. I don't know what I messed up though. The calc isn't hard it's the algebra that trips me up. Jun 5 comment Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? Thanks! I'm working it out now. Jun 5 comment Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? How's that? :) . Jun 5 asked Where is $f(x)={(x^2+2x-48)}/{x^2}$ increasing? decreasing? Jun 4 comment How is this function never decreasing?! dang it! Ln's can't be negative! Thanks lol Jun 4 asked How is this function never decreasing?! Jun 4 comment e's with x in the exponents: Gotta solve for x. I didn't realize one of the answers was "There are no x-intercepts" lol Thanks! Jun 4 comment e's with x in the exponents: Gotta solve for x. Yes I see how this works now. Thanks for your help.
