Question 1127391: Say that a business determines its profit function is: P ( x ) = x^2 - 6 x + 1 where X is the number of units produced in thousands and P ( x ) is the profit made in thousands of dollars.
Does this mean that the business should produce 3,000 units to maximize its profit

Yes, but the equation should be:
+-x%5E2+%2B+6x+%2B+1+
in order for the peak to be a maximum
and for +x+ to be positive when +P%28x%29+
is a maximum
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+-x%5E2+%2B+6x+%2B+1+%29+

Max profit occurs when x = -b/(2a) = 6/2 = 3

Let me make couple of notices:

    1.  The given quadratic function has a MINIMUM  at x= 3 thousands.


    2.  The given quadratic function HAS NO a MAXIMUM at x= 3 thousands.


Therefore, the question is IRRELEVANT to the given part.

Not only irrelevant - it CONTRADICTS to the given part.

If you want to learn the basics on minimum and maximum of quadratic functions,
two groups of lessons were developed in this site specially for you :

    - HOW TO complete the square to find the minimum/maximum of a quadratic function
    - Briefly on finding the minimum/maximum of a quadratic function
    - HOW TO complete the square to find the vertex of a parabola
    - Briefly on finding the vertex of a parabola

    - A rectangle with a given perimeter which has the maximal area is a square
    - A farmer planning to fence a rectangular garden to enclose the maximal area
    - A farmer planning to fence a rectangular area along the river to enclose the maximal area
    - A rancher planning to fence two adjacent rectangular corrals to enclose the maximal area
    - Using quadratic functions to solve problems on maximizing revenue/profit
    - OVERVIEW of lessons on finding the maximum/minimum of a quadratic function (*)

A convenient place to observe all these lessons from the  "bird flight height"  is the last lesson in the list,  marked by  (*).
