Marsha wants to determine the vertex of the quadratic function f (x) = x2 - x + 2. What is the function's vertex?

The formula for finding the vertex of a parabola is: x = - b/2a

Once you find the x value, substitute it back in to the function to find the y value.

x = 1 / (2*1)

x = 1/2

y = (1/2) ^2 - (1/2) + 2

y = (1/4) - (1/2) + 2

y = 1 3/4

vertex (1/2, 1 3/4)
