Question 1169204
<font face="Times New Roman" size="+2">


You have a quadratic function with a negative lead coefficient, so the graph is a concave down parabola.  Therefore, the value of the function at the vertex is the maximum value of the function. The value of the independent variable at the vertex of a parabola is given by the additive inverse of the first-degree term coefficient divided by 2 times the lead coefficient.  Evaluate the function at the value of the independent variable at the vertex to find the maximum value of the function.  You can do your own arithmetic.
