$\text{Nothing really needed in 1a) except for algebra.}\\ \begin{align*}\frac{f(x+h)-f(x)}{h}&= \frac{[(x+h)^2-4(x+h)]-[x^2-4x]}{h}\\ &= \frac{x^2+2xh+h^2-4x-4h-x^2+4x}h\\ &= \frac{2xh+h^2-4h}{h}\\ &= 2x+h-4\end{align*}$

Just curious, why do you browse the forum so often.

Pretty much every time I ask a math question, bam. 1 second. Answered.

Or.. you could just say thank you and move on? Rui is one of our best mods who pretty much takes time out of his busy uni schedule to answer questions (let's remember that majority of us don't get paid to do this.. we do it because we want to see students like yourself succeed).

Thread closed as question is answered.

Search the forums now!

We have moved!
