Question

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

Answer 1

To find a vertex of a parabola, use the equation -b / 2a to find the AOS.


`y = x^(2) -x + 2`


`(-1)/(2)`

If the x - coordinate of the equation is
`-(1)/(2)`, then plug that value of x in:


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

The y-coordinate is
`(11)/(4)`

Answer 2

2 and 1/4
