Explanation Given Information: The function that gives the amount of profit y earned by recycling x tons of material is y = − 50 x 2 + 7 , 000 x − 65 , 000 and the following graph shows the profit function of the recycling business for recycling tons of material. Consider the equation, y = − 50 x 2 + 7 , 000 x − 65 , 000 Graph of the equation using the TI-83 graphing calculator is as follows: Follow the steps as mentioned below to determine the solution of the equation y = − 50 x 2 + 7 , 000 x − 65 , 000 using TI- 83 graphing calculator: Step 1 : Press “ Y = ” key and insert the equations as, Y 1 = - 50 X 2 + 7000 X − 65000 Step 2 : Press the “WINDOW” key and set the values as, X min = 0 Xmax = 140 Xscl = 20 Ymin = − 60000 Ymax = 200000 Yscl = 20000 Xres = 1 Step 3 : Then press the “GRAPH” key
