I gather it means, using the derivative as a definition of a Limit
namely $\bf \lim\limits_{h\to 0}\ \cfrac{f(x+h)-f(x)}{h}$

3mar · Answer

Of course.
With my pleasure!


Are you aware of the power rule of differentiation?

mintiruki · Answer

Yeah, @jdoe0001 that is what we're supposed to use. I looked at my teacher's work and there was one part that didn't make sense to me.

mintiruki · Answer

@3mar, yes! But I don't think we're supposed to use that here, we're supposed to use what jdoe001 wrote.
