Question

What are the coordinates of the vertex of y = x^2 - 4x - 5?
(2, -9)
(2, -5)
(-2, 7)
(-2, -5)

Answer 1

y=−2x−5

Answer 2

-2, -5 :) Please give a medal

Answer 3

Or fan if this helped

Answer 4

Thank you!

Answer 5

No problem. :D

Answer 6

i think it is a good thing to show your work
and also don't you need to complete the square
then turn into vertex form

Answer 7

What? @helpme1.2 ???

Answer 8

vertex form: y = a(x-h)^2+k
y = x^2 - 4x - 5
y = (x^2-4x +4)-5-4
y = (x-2)^2-9
now that is in vertex form
which means
the coordinates would be (2,9)

Answer 9

(2 -9)*

Answer 10

does this make sense @Nikkeyiboo ?
