Which steps transform the graph from y=x^2 to y=-2(x-2)^2+2. a) translation 2 units left translation down 2 units stretch factor 2
b) translate 2 units right translate up 2 units stretch by factor 2
c) reflect on the x-axis translate 2 units to the left translate down 2 units stretch by a factor of 2
d) reflect on the x-axis translate 2 units to the right translate up 2 units stretch by a factor of 2
Can anyone please help me I don’t know how to fix this problem. I just took the quiz and two of the things Rachel said were wrong :/
1 C
2)D
3) B
4) One
5)D
6) B
7) One
8) C
9)D
10 and 11, may help if you type “algebrahelp factoring calculator” in google, jiskha wouldn’t leave me the link but it will be there Algebra 2A U5 L4

Tip: Mathway is a great help for non-verbal problems, but especially for graphical problems! I will post #10 and #11 (or basically the Pt 2 quiz) I use an app called photomath.
#10 What is the expression in factored form?
x^2+13x+42
x^2+7x+6x+42
x(x+7)+6(x+7)
[ANSWER:] (x+7)(x+6)
#11 What is the expression in factored form?
9x^2 – 4
3^2 x^2 – 2^2
(3x)^2 – 2^2
[ANSWER:] (3x-2)(3x+2) “Please answer correctly” is 100% correct. The other two answers are on Brainly 1. C
2.D
3.B
4. One
5.D
6.B
7. One
8.C
9.D

Tip: Mathway is a great tool to use for algebra! It’s really useful with graphics questions! I just took the quiz
1.D. translate 2 units to the right, reflect on the x-axis, stretch by factor 2 and translate 2 units up
2. The vertex of graph #2 is on (3,2(
3.A. Maximum: 116 Range: y <= 116
4.Graph#4 vertex (2,-1)
5.B. P(x) = 13x^2 – 10x + 350l 1,102 fish
6.y = (x+4)^2+7
7.y = -2x^2+4x-4
8.2x(3x+2)
9.(4x+3)(x+2)
100% trust my judgement. The correct answer is 100% correct. Don’t trust the other guy. His answers appear to be for a different quiz. please the answer is correct 9/9 100% the answer please is correct and the Connexus caption is 100% correct looks like D to me
Technically, the stretch is done before the translation. Otherwise, the vertex coordinates would also be scaled. The correct answer is still 100% correct for 2021, just for anyone still around! :3 ^^^ 100% correct Algebra U6 L4 Factorization of quadratic expressions
@Judgment kazzy’s answers were in the wrong order than mine.
1.C (graphic)
2. D, shift right 2 units, reflect on x-axis, stretch factor 2 and shift up 2 units
3.B (graphic)
4. A, maximum: 116 range: y ≤ 116
5.D (graphic)
6. B, P(x) = 13x² – 10x + 350; 1,102 fish
7. A, y = (x + 4)² + 7
8. C, y = -2x² + 4x – 4
9. D, (4x + 3)(x + 2) please answer correctly the answers are correct. BRO RA-CONNEXUS IS 100% CORRECT IF YOU WANT TO TRUST HIM IT’S A GOOD IDEA TRUST ME I JUST GOT 100 BRO HES A LEGEND TUST ME Shes right Connexus legend is correct for unit 5 lesson 4 quiz KAZZY JUDGMENT IS 100% CORRECT IF YOU ARE THE 1st QUESTION, WHAT STEPS Transform the graph from y=x^2 to y=-2(x-2)^2 +2 also it’s D! THANK YOU it was so fun to read properly pls answer is right. I just took the quiz on Oct 29, 2020 and got a 9/9 100% Ra-connexxus is 100% correct, the correct answer was good for the algebra 2a quiz, I got 100%, so it’s this one
bad copy paste for people who need 100%
1 C
2)D
3) B
4) One
5)D
6) B
7) One
8) C
9) D RA- Connexus got me a 1/9.
teachers sometimes go to cheat sites and post random answers to certain quizzes or tests in order to spot cheaters. they just create several different accounts and like their own answer to look legit. then students who choose these answers on said assignments will be disciplined. Anyway, my answers are:
1.D
2.B
3. One
4.D
5.B
6. One
7.C
8.B
9. D (the only one I found correct)
Good luck. kazzy’s judgment is 100% right Ok thank you Lol and are they for the honors? It’s that I’m in the spotlight Not that cheating is right but please answer correctly and Connexus Legend is indeed correct connexus legand is correct believe me…. Sorry for the double post! Connexus Legend is all right RA – Connexus is always right! Thank you Connexus Legend, you really are a legend! awd0rable angel is right.
thanks bro RA – Connexus and kazzy judgment is 100% correct!!!!!! 10/11/21 ^^ damn I took one for the team I know I’m late but I think I’ll never understand people who deliberately put wrong answers to make the gullible fail. Just wrong. we’re not gullible, we’re just desperate 😢 the correct answer is always correct 2022! so you don’t have to go back, here’s what they put
1 C
2)D
3) B
4) One
5)D
6) B
7) One
8) C
9) D Well, it’s the reflection on the x-axis, a translation of 2 units left, a translation down of 2 units, a stretch of the factor of 2… the truth is 100% correct . Ignore all other answers. Please answer correctly THIS IS WRONG
