7-115.
1. Let g(x) = . Homework Help ✎

1. Calculate the average rate of change of g(x) from x = 5 to x = 6.

2. Write the expression for the average rate of change of g(x) from x = 5 to x = 5 + h.

3. Evaluate your expression from part (b) as h → 0.

$\frac{\frac{10}{6}-\frac{10}{5}}{6-5}$

$\frac{\frac{10}{5+h}-\frac{10}{5}}{5+h-5}$

$\lim_{h\rightarrow 0}-\frac{2}{5+h}=?$
