Question

Can someone tell me if when you graph this it goes up or down?
Y=-(x-2)^2

Answer 1

You can answer that yourself. If you have a positive number and you square it will the result be positive or negative?

Answer 2

well it reflected over the y axis i believe lol

Answer 3

so it will go down?

Answer 4

yes, but do you understand what bearbear means?

Answer 5

no the equation would probably be reflected that doesn't mean it goes up or down

Answer 6

what's the original equation?

Answer 7

so will it look like this click the link

Answer 8

is that a quadratic ?

Answer 9

idk thats just one of my chocies

Answer 10

for any value of x, (x-2)^2 will always be positive correct?, or if x = 2, it will be 0.

Answer 11

so it looks like this

Answer 12

wait im getting a photo of how it looks like but if you have a ti-84 calculator
go to y= then go to the button where it has "x,t,o w/ a slash in a middle, n" which is located right next to the alpha button then go to the x squared then press graph

Answer 13

no, that is wrong katie

Answer 14

@ katie, do you want to learn or just want the answer?

Answer 15

both lol

Answer 16

oh wow this is so easy do you have a graphing calculator ??? omg you should get on if you don't have one but anyways you can always graph it, do you know how to graph the equation ??

Answer 17

no

Answer 18

okay katie,
it is very simple. at x = 2, y = 0. for all other values of x, y is negative. correct?

Answer 19

Because any number squared will be positive, and any positive number multiplied by -1 will be negative.

Answer 20

so you will have an inverted parabola with its vertex at x = 2

Answer 21

ohh okay that is a chocie thanks guys
