Question 322210
<font face="Garamond" size="+2">


This is a parabola.  Since the lead coefficient is negative, the parabola opens down, and therefore the vertex is a maximum.  The value of the independent variable (*[tex \Large t] in this case) at the vertex is the negative of the coefficient on the first degree term divided by two times the lead coefficient.
