Answer 1

http://mathway.com/graph_image.aspx?p=y=-1(x-2)^2+3?p=520?p=450?p=False?p=False?p=False?p=False?p=True?p=False?p=True?p=True?p=?p=?p=?p=?p=4

Thats a graph, can you do the rest?

Answer 2

maybe.. not completely sure.. i suck at math

Answer 3

do you know what a vertex is?

Answer 4

no

Answer 5

Vertiex:
-The highest point; the top or apex.

(google dictionary)

do looking at the graph i sent you, what is the highest point?

Answer 6

vertex*

Answer 7

2,3 ?

Answer 8

yes! good job:)

Answer 9

AHHH thankyou!!!!!!!!!(((((::

Answer 10

can you help me with the rest of my awful test?

Answer 11

hahah no problem:) glad i could help

Answer 12

um sure.

Answer 13

What are the x– and y–intercepts of the graph of y = x2 – 10x + 21?

Answer 14

http://mathway.com/graph_image.aspx?p=y=x2-10x+21?p=520?p=450?p=False?p=False?p=False?p=False?p=True?p=False?p=True?p=True?p=?p=?p=?p=?p=4

theres the graph.

were there supposed to be things after x- and y- ?

Answer 15

oh just kidding.

Answer 16

???

Answer 17

forget the question i asked. um so you see the graph?

do you know what x and y intercepts are?

Answer 18

yea

Answer 19

y = –1(x – 2)2 + 3

y=(-x+2)2 + 3

y= -x^2 + 4 + 3

y= -x^2 + 7
y= x^2 - 7

so thats the y intercept.

use this ==> y = –1(x – 2)2 + 3 and solve for x to get the x intercept

Answer 20

y=(1x)5 ?

Answer 21

but you're solving for x:) so it should look like this x= ______

Answer 22

idk how id do that...

Answer 23

y = –1(x – 2)2 + 3
y=(-x+2)2 + 3
y= -x^2 + 4 + 3
y= -x^2 + 7
y= x^2 - 7

good so far? its what i did earlier.

y= x^2 - 7
7+y=x^2
x= \[\sqrt{7+y}\]

Answer 24

i might be wrong... eek. i think i am.

Answer 25

i'll just guess, i guess..and I can ask you my next question?

Answer 26

okay

Answer 27

Which statement describes the translation of y = – (x – 2)2 – 2 from standard position?

these are the answers to choose from

Moved up and to the left.
Moved up and to the right.
Moved down and to the left.
Moved down and to the right.

Answer 28

Heyyy i got the one i though i was wrong on.

x= http://mathway.com/math_image.aspx?p=(SMB02RSMB033SMB02rSMB03+2,0),(-SMB02RSMB033SMB02rSMB03+2,0)?p=167?p=22
y=(0,-1)

and for the last question it's : to the right.

Answer 29

moved up or down?

Answer 30

not sure. i'm guessing down

Answer 31

What is the range of the graph of y = 5(x – 2)2 + 7?
Answer
y 2
y 7
y 7
y 2

Answer 32

*** \[y \ge 2\]
\[y \le 7\]
\[y \ge 7\]
\[y \le 2\]

Answer 33

What is the equation of the graph below in vertex form, y=a(x – h)2 + k? Using complete sentences, explain how you developed your equation

Answer 34

i actually got y≥7/5
so. i dont know.. i'd go for y≥2-- sorry about that.

um, i feel like i'm doing your test for you.. which is cheating. so why dont you give it a try.

Answer 35

ok..
