A company is planning to manufacture affordable graphing calculators. The fi xed monthly cost will be $50,000 and it will cost $25 to produce each calculator. a. Write the cost function, C, of producing x graphing calculators. b. Write the average cost function, C, of producing x graphing calculators. Summary, Review, and Test 409 c. Find and interpret C(50), C(100), C(1000), and C(100,000). d. What is the horizontal asymptote for the graph of this function and what does it represent?

Overview week of 9/12/16 3.3 Rules of Differentiation Power of X: d n (n1) Power Rule: / Xdx= nX Quotient Rule: / f(x)/g(x) = [(f(x) * g(x)) – (f(x) * g(x))] / [g(x)] 2 dx Product Rule: / [dxx) * g(x)] = [f(x) * g’(x)] + [g(x) * f’(x)] Chain Rule: / [dxg(x))] = [f(g(x))]’ * g’(x) Constant Multiple: Power rule d /dx(cf(x)) = c * f ’(x) 3.4 Product and Quotient Rules Product Rule: While [f(x) +/ g(x)]’ = f ‘(x) +/ g’(x), The same does not apply to multiplication And division. [f(x)g(x)] ≠ f ‘(x) * g’(x) Instead: [f(x)g(x)] = [f(x) * g’(x)] + [g(x) * f’(x)] Products of multiple functions: (fg)’ = f’g + fg’ (fgh)’ = f’gh + fg’h + fgh’ (fghi)’ = f’ghi + fg’hi + fgh’i + fghi’
