Best ResponseYou've already chosen the best response.2yes \[y = 4x^2+1\] \[\frac{d}{dt}y = \frac{d}{dt}4x^2+\frac{d}{dt}1\] \[\frac{dy}{dt} = \frac{dx}{dt}8x+0\]

Best ResponseYou've already chosen the best response.2the key is seeing that x' is not defined as dx/dx in this case, so we take a derivative implicitly with respect to time, and not to x
