I have the function: I need to "find the derivative by the limit process". Using: My work: The two 5x's go away, the 5Δx and Δx go away, so I'm left with 12, which isn't the answer. I'm lost.

Thanks a lot. I need to start using instead of Δx, since Δx is pretty confusing.
I agree with this.
New question... There's just way too many things on my paper and I'm just lost now .
This one will take some doing, here's the first bit, now gettting expanding!
