Concept explainers
Advertising A small manufacturing firm collected the following data on advertising expenditures
Draw a
scatter diagram of the data. Comment on the type of relation that may exist between the two variables.Use a graphing utility to find the quadratic function of best fit that models the relation between advertising expenditures and total revenue. Use this model to determine the optimal level of advertising.
Use the model to predict the total revenue when the optimal level of advertising is spent.
Use a graphing utility to draw a scatter diagram of the data, and then graph the quadratic function of best fit on the scatter diagram.
