The cost of an appliance whose purchase price is $600 and annual hydro cost is $115 is given by the function C(n) = 600 +115n , where C is the annual cost, in dollars, and n is the number of years. i) Sketch a graph of C versus n for the entire function in a paper-pencil style. Clearly label the axes, scale on both axes, the asymptote(s), and the intercept(s). ii) How is the graph of the entire function different from the graph for the real-life situation? iii) Determine increasing interval(s) of the function if it exists.
