To find the vertex of the equation, we need to use the formula x = -b/2a to find the x-coordinate of the vertex, and then substitute the x-coordinate into the equation to find the y-coordinate. 
The equation is not given, so we cannot calculate it, but we do know that the vertex of a parabola in standard form (y = ax^2 + bx + c) is (-b/2a, c - b^2/4a). 
In this case, since the coefficient of x^2 is positive (a > 0), the parabola opens upwards, and the vertex is the lowest point on the graph. 
Therefore, the best choice is C, because it states that the vertex is the highest point on the graph, which is incorrect.
