Answer:
is your average rate of change,
Step-by-step explanation:
average rate of change is
, by slope formula
simplify this to get
, which is the definition of the derivative as h goes to 0
![\lim_{h \to 0} \frac{f(a+h)-f(a)}{h}](https://tex.z-dn.net/?f=%5Clim_%7Bh%20%5Cto%200%7D%20%5Cfrac%7Bf%28a%2Bh%29-f%28a%29%7D%7Bh%7D)
since you defined x=a, we can substitute a for x and vice versa to find our derivative.
![\lim_{h \to 0} \frac{(2x^2+\frac{1000}{x+h})-(2x^2+\frac{1000}{x})}{h}](https://tex.z-dn.net/?f=%5Clim_%7Bh%20%5Cto%200%7D%20%5Cfrac%7B%282x%5E2%2B%5Cfrac%7B1000%7D%7Bx%2Bh%7D%29-%282x%5E2%2B%5Cfrac%7B1000%7D%7Bx%7D%29%7D%7Bh%7D)
simplifying
(your average rate of change)
