Find an example online of a graph used in real life. Please provide the link to the web page by using the link button in the editor. Describe at least one mathematical feature of the graph (e.g. shape, slope, coordinates, axes, quadrants, etc.) and how the feature/graph can help us to analyze the real-life situation.

Consider the following profit functions: P(x) = 5000 - (1000/(x-1)) , x > 1 P(x) = 5000 - (1000/(x-2)) , x > 2 where P(x) indicates the annual profit in thousands of dollars, and x is the number of items sold in thousands. Find out the number of items sold, in each case, to achieve the annual profit value of 4000.

Please provide detailed solution: What can you say about the differentiability of fg at x = c in each of the following cases? (Here the function fg is defined by fg(x) = f(x)g(x)). (a) f is differentiable at c, but g is not. (b) f is not differentiable at c, and neither is g. (c) both f and g are differentiab

You are given two points representing the number of items sold at a particular price. From these two points, a linear demand function is constructed. You are also given information on the cost of each item so that you can construct a cost function. From the demand function you can form a revenue function and finally the profi
