    Graph it? Hmm this one is going to be a little tricky :) The vertex is located at some fractional points. Do you remember how to complete the square? That's what we'll need to do in order to get this into vertex form.

    for a quadratic equation you can complete the square or use for this form ax^2 +bx + c find vertex with -b/2a

    plugging -(-7/2(2) =?? once you get that ;ug it back into your equation for x then you will get the vertex point (x,y)
