    I'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.

    If 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.

    It's a positive value, I would imagine it's increasing. Hmm, thinking.

    Yeah I would assume since its positive that It would be increasing
