Best ResponseYou've already chosen the best response.1okay well what is the derivative of e^x?

mathdood

Best ResponseYou've already chosen the best response.1it is e^x*x' and the derivative of x is 1 so you have e^x but in this case since you have 2x and 0.2x you need to bring those down and differentiate you know what I mean?

Best ResponseYou've already chosen the best response.1crazy eh derivative of e^x is e^x!!

Best ResponseYou've already chosen the best response.1but that it isn't the end of your problem okay do you know how to take simple derivative like x^2? like do you know the power rule?

Best ResponseYou've already chosen the best response.1right just making sure.

Best ResponseYou've already chosen the best response.1Okay so when you see e^x you have e^x and when you see e^2x you get e^2x*(2x)' the ' means derivative. You understand? If not I don't mind continuing at all.

Best ResponseYou've already chosen the best response.0ok.. e^2x * (2x)' is e^2x

Best ResponseYou've already chosen the best response.1no what is the derivative of 2x?

mathdood

Best ResponseYou've already chosen the best response.1no that is the integral of 2x think about it like this. The derivative is the rate of change of the function so you are looking for the how fast the function is changing. so how fast is 2x changing?

Best ResponseYou've already chosen the best response.1sorry not how fast but by how much is it changing for each value of x

Best ResponseYou've already chosen the best response.1yes =) just for fun what is the derivative of 2?

Best ResponseYou've already chosen the best response.1sorry I know I am dragging this out I just want to help you understand. Well think how much is the function y=2 changing over time right!! =)

Best ResponseYou've already chosen the best response.1Anyway back to the problem

mathdood

Best ResponseYou've already chosen the best response.1so if (e^2x)' = 2e^2x then what do you think (4.2e^2x)' = ?

Best ResponseYou've already chosen the best response.1good stuff dude now how about (−2.9e^(−0.2x))' = ?

mathdood

Best ResponseYou've already chosen the best response.1yes you got it =) keep going you can do this

Best ResponseYou've already chosen the best response.1I didn't check on the calculator but it looks right dude so now you just have to put the whole thing together you want to show me what that looks like?
