Expert Answers

Another way of determining the vertex of the graph is by using a graphing calculator.  Graph of y = x^2 + 3x - 4

 

The vertex is (-1.5, -6.25).

If you do not have one, I have included a website that has an online graphing calculator.  Besides vertex points, this website will also calculate x- and y-intercepts.
