Question

Find the vertex of the parabola y = x2 - x + 5.

Simplify both coordinates and write them as proper fractions, improper fractions, or integers.

Answer 1

(1/2, 19/4)

Explanation:

So the formula is y=-b/2a.

a= 1

b= -1

Plug in the values to get x=1/2.

you then plug in 1/2 to get the y

you end up with 19/4.

Your vertex ends up as (1/2, 19/4).

hope this helped!!
