To determine The value of x for which company makes a profit where profit are given by equation P = 2 x 2 − 12 x − 32 . Here, P is profit in hundreds of thousands of dollars and x is in the amount, in hundreds of dollars, spent on advertising. Explanation Given: The profit equation, P = 2 x 2 − 12 x − 32 Explanation: For the company to make a profit, P > 0 That implies, 2 x 2 − 12 x − 32 > 0 To determine the solution of the above function in the window [ − 10 , 10 ] by [ − 50 , 50 ] . Use Ti-83 to plot the graph of the function: Step 1: Press the [ Y= ] key, then there will appear the equations for y . Step 2: Enter the equations in Y 1 . Here, Y 1 = 2 x 2 − 12 x − 32 . Step 3: Press [ WINDOW ] and then edit the values as X min = − 10 X max = 10 X S c a l e = .5 Y min = − 50 Y max = 50 Y S c a l e = 1 Step 4: Press the [ GRAPH ] key to plot the graph
