Vertex = (.5, 1.75)

First, you must find your x-value, which is represented by h in the formula h=-b/2a. In this equation, A = 1, B = - 1, C = 2, which gives you - 1 (-1) / 2 (1) = 1/2 =.5. Now that you know your x-value is. 5, you can solve for y. Plug in your x-value accordingly: (.5) ^2-.5+2 = 1.75. x =.5, y = 1.75, therefore, your vertex is (.5,1.75)

Vertex x = - b/2a so x = 1/2. Plug in x and u get 3/2
