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. 

$y = x^{2} -x + 2$

$\frac{-1}{2}$

If the x - coordinate of the equation is $-\frac{1}{2}$, then plug that value of x in:

$y = \frac{1}{4} + \frac{1}{2} + 2$

The y-coordinate is $\frac{11}{4}$

Answer 2
