Answer:</h2><h2>
The total cost (C) charged by the internet service provider = $65 + $18(n)</h2>
Step-by-step explanation:
Initial fee charged by the servic eprovider = $65
Cost per hour of labor for office internet installation = $18
The cost per hour be $18
Cost per two hours = 18 * 2 = $36
Cost per n number of hours = $18 (h)
where h represents the number of hours
The total cost (C) charged by the internet service provider = $65 + $18(n)

Basic Power Rule:
- f(x) = cxⁿ
- f’(x) = c·nxⁿ⁻¹
Step-by-step explanation:
We are given the following limit:
Let's substitute in <em>x</em> = -2 using the limit rule:
Evaluating this, we arrive at an indeterminate form:
Since we have an indeterminate form, let's use L'Hopital's Rule. Differentiate both the numerator and denominator respectively:
Substitute in <em>x</em> = -2 using the limit rule:
Evaluating this, we get:
And we have our answer.
