How do I do this question (in comments)? Steps please.

Answer 2

it's just like the rate of change of the function close to that point.\[\frac{\Delta y}{\Delta x }=\frac{f(1.004)-f(1)}{1.004 - 1}\]

Answer 3

there's an extra zero placed there, but you get the point...

Answer 4

So is E the answer?

Answer 5

yes it certainly seems so

Answer 6

I somehow got E, but I don't remember how and it wasn't the same method, it was some weird circly method and now it's bothering me.

Answer 7

\[\frac{f(1.04)-f(1)}{1.04 - 1}\]\[= \frac{10.96-10}{0.04}\]\[=\frac{0.96}{0.04}= 24\]
