Book Sales As OHaganBooks.com has grown in popularity, the sales manager has been monitoring book sales as a function of the website traffic (measured in thousands of visits per day) and has obtained the following model:
a. On average, how many books per day does the model predict that OHaganBooks.com will sell when it has 60,000 visits in a day? 100,000 visits in a day? 160,000 visits in a day?
b. What does the coefficient 1.75 tell you about book sales?
c. According to the model, approximately how many visitors per day will be needed to sell an average of 300 books per day?

- Consider the function f(x) = x²-1. (a) Find the instantaneous rate of change of f(x) at x=1 using the definition of the derivative. Show all your steps clearly. (b) Sketch the graph of f(x) around x = 1. Draw the secant line passing through the points on the graph where x 1 and x-> 1+h (for a small positive value of h, illustrate conceptually). Then, draw the tangent line to the graph at x=1. Explain how the slope of the tangent line relates to the value you found in part (a). (c) In a few sentences, explain what the instantaneous rate of change of f(x) at x = 1 represents in the context of the graph of f(x). How does the rate of change of this function vary at different points?arrow_forward1. The graph of ƒ is given. Use the graph to evaluate each of the following values.
