Question 1183591

Determine  the coordinates the minimum point from the graph of the quadratic function 
f(x)=x^2+6x-1
<pre>You don't need to Complete the Square in order to find the minimum point.  Unless, of course, you're asked to work the problem by Completing the Square.
You'd need a GRAPHING device to graph the equation, and then use that device to find the vertex.
OR
The minimum occurs where {{{system(matrix(1,3, x, "=", - b/(2a)), matrix(1,2, or, where), matrix(1,3, x, "=", - 6/(2*1)), matrix(1,2, or, where), matrix(1,3, x, "=", - 6/2), matrix(1,2, or, where), matrix(1,3, x, "=", - 3)))}}}
       Minimum occurs at {{{system(matrix(1,3, f(- b/(2a)), "=", x^2 + 6x - 1), matrix(1,2, or, "at:"), matrix(1,3, f(- 3), "=", (- 3)^2 + 6(- 3) - 1), matrix(1,2, or, "at:"), matrix(1,3, f(- 3), "=", 9 - 18 - 1), matrix(1,2, or, "at:"), matrix(1,3, f(- 3), "=", - 10)))}}}
                         {{{highlight_green(matrix(1,4, Minimum, "point:", "(- 3,", "- 10)"))}}}
