Question

True Value Fabricators produces circular iron cast disks to be used as endplates. The cost of the disks is a quadratic function of the diameter. 1inch diameter cost $12.00, 2 inch cost $18.00, 3 inch cost $28.00, 4 inch cost $42.00, 5 inch cost $60.00. In this situation, what are the independent and dependent variables? B.) Sketch a scatterplot of the data. Label the axes. C) Enter the data into the graphing calculator. Use transformations of y=x2 to determine a representative function for the data set in y=a(x-h)2 +k form. D) What would be a reasonable domain and range for this function? E) Find each of the characteristics and explain their meaning in the problem situation Vertex, Axis of symmetry, y-intercept, x-intercept. need Value and Meaning in Problem Situation. F) What would be the cost of a disk with a diameter of 12 inches? G) If the cost of the disk is $522, what would be the diameter of the disk?
