Question

The question is number 12. URGENT PLEASE

Answer 1

Answer: Choice C

We have an expression in the form

`(f(x+\Delta x)-f(x))/(\Delta x)`

where the
`\Delta x` term is approaching 0, which is what the "lim" indicates (we're applying a limit).

Note how in
`f(x+\Delta x)`, we effectively replace every copy of x with
`x+\Delta x`

Choice D is close, but it's missing the "lim" notation, so it's not 100% accurate.
