    I need to sketch a graph of the revenue function to verify my answer. I found the max revenue which was R(6842)=318720.47

    6. x =(approx.) 6842 7. R(6842)= 318720.47 3. R(x)= x*130e^-0.000150x

    4. R(100)= 12806.45 R(500)=12060.67 R(1000)=11189.20 R(5000)=6140.76 5. R'(x)= (130 - 0.019x)e^0.000150x

    it says you can just use a program to graph it. Put your equation in here https://www.desmos.com/calculator

    scroll down to the bottom and you'll see the max for the function as 318,829 at x = 6666.67, which is slightly different from yours

    I just typed in your equation. If you use desmos, just keep zooming out until you see the curve go up and tail off toward the right. If you use wolfram, add the restriction 0<x< a big number. Keep increasing/decreasing the number until you see as much of the graph as you want.
