Question

y=x^2-x-23

Answer 1

y = x^2-x-23 find the vertex


The vertex is a point in the form (x,y).


We first find x.


x = -b/2a


x = -(-1)/2(1)


x = 1/2

Answer 2

To find y, replace every x in the given function with 1/2 and do the math.


y = (1/2)^2-(1/2)- 23


y = 1 - 1/2 - 23


y = -45/2


The vertex is (1/2, -45/2).

Answer 3

is vertex what the question is? or is it the roots?

Answer 4

y=x^2-x-23
Solving the equation for x we get x=(5.32 & -4.32).
The mid point is 5.43-4.32=1/2=.5
y=.5^2-.5-23

Answer 5

y=.25-.5-23
y=.25-23.5
y=-23.25
The VERTEX(.5,-23.25)
