Best ResponseYou've already chosen the best response.1I'm thinking of it like this... in terms of differentials, \[\large\rm y=3x^2+1\]Find instantaneous rate of change,\[\large\rm dy=6x\cdot dx\]At x=2, y has a rate of change of 3 (meaning dy=3). Plug these values in and solve for dx, the rate of change of x.

Best ResponseYou've already chosen the best response.1If the idea of differentials is confusing, you can instead take derivative the normal way that you're used to.\[\large\rm \frac{dy}{dx}=6x\]And hten sort of uhh... "multiply" the dx to the other side.

Best ResponseYou've already chosen the best response.1It's a positive value, I would imagine it's increasing. Hmm, thinking.
