Find the y-coordinate of the vertex of the parabola whose equation is y = x2 - x + 2.

the y-coordinate of the vertex: 7/4

Step-by-step explanation:

y = x^2 - x + 2

axis of symmetry (x-coordinate of vertex) = -b/2a = - (-1)/2(1) = 1/2

Plug in x = 1/2 to find the y-coordinate of the vertex:

y =  (1/2)^2 - (1/2) + 2

y = 1/4 - 2/4 + 8/4

y = 7/4

Vertex (1/2 , 7/4)

the y-coordinate of the vertex: 7/4

X = 4
