If f(x)=2x^2+(1000/x), find the average rate of change of f(x) from x=a to x=a+h.

galina1969 [7]

Answer:

$\frac{\frac{1000}{x+h}-\frac{1000}{x}}{h}$ is your average rate of change,

Step-by-step explanation:

average rate of change is

$\frac{f(a+h)-f(a)}{a+h-a}$ , by slope formula

simplify this to get $\frac{f(a+h)-f(a)}{h}$ , which is the definition of the derivative as h goes to 0

$\lim_{h \to 0} \frac{f(a+h)-f(a)}{h}$

since you defined x=a, we can substitute a for x and vice versa to find our derivative.

$\lim_{h \to 0} \frac{(2x^2+\frac{1000}{x+h})-(2x^2+\frac{1000}{x})}{h}$

simplifying

$\lim_{h \to 0} \frac{\frac{1000}{x+h}-\frac{1000}{x}}{h}$ (your average rate of change)

Write at least two examples that illustrates why logb (x+y) =/= logb(x) + logb(y).

Eddi Din [679]

The examples that illustrates why logb (x+y) =/= logb(x) + logb(y) are:

$Log3_2 + Log 6_2\\Log12_2 + Log 4_2\\Log4_2 + Log 4_2$

<h3>Calculations and Parameters</h3>

Based on the fact that they are of the same base,

Mathematical operations can be done on them as shown above.

Thus, $Log3_2 + Log 6_2\\Log12_2 + Log 4_2\\Log4_2 + Log 4_2$

This is because they are of the same base and this is why mathematical operations can be performed on them.
