Best ResponseYou've already chosen the best response.4So they gave you \[\Large y = 3xe^{x}\] right?

Best ResponseYou've already chosen the best response.4I'm getting \[\Large \frac{dy}{dx} = 3e^{x}(x1)\] as well

Best ResponseYou've already chosen the best response.4I'm using the idea A*B = 0 means either A = 0 or B = 0
