Question 1 Suppose that the price per unit in dollars of producing a cell phone is given by p(x) = 44 - 0,0125x and the quantity of phones produced is given by q(x) = x. The revenue function R(x) is price times quantity, expressed in function notation as: R(x) = p(x) . q(I), the price function multiplied by the quantity function. 1. Use the given information to create and simplify the equation for the revenue function R(x). R(I) = 2. Will the vertex of R(x) be a maximum or a minimum? Select an answer How can you tell from the equation itself (before you graph it)? Select an answer 3. Graph the revenue function in your calculator. Set your WINDOW to xmin:0, xmax:3500, and ymin: 0, ymax: 45000 Use your calculator to find the (x, y) coordinates of the vertex of R(x), (hint: it will be a whole number between 1400 and 1800) and explain what it means in terms of cell phones and revenue: Vertex: Select an answer O 4. It also makes sense that x needs to be greater than or equal to 0 in this case (no producing negative amounts of phones). R(x). Sketch the graph of R(x), 45000 42500 40000 37500 35000 32500
