Which steps transform the graph of y=x^2 to y=-2(x-2)^2+2.
a) translate 2 units to the left translate down 2 units stretch by factor 2
b)translate 2 units to the right translate up 2 units stretch by the factor 2
c)reflect across the x-axis translate 2 units to the left translate down 2 units stretch by the factor 2
d)reflect across the x-axis translate 2 units to the right translate up 2 units stretch by the factor 2
Can someone please help me, not sure how to do this problem.

Hint: Mathway is a great help with non-word problems, but especially graphing problems!
I'll 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)

2.Graph#2 vertex 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

Hint: Mathway is a great tool to use for Algebra! It is really helpful with graphing questions!
Pls Answer correctly is 100% correct. Don't trust the other guy. His answers seems like they're for a differently quiz.
Plz answer right and Connexus Legend are 100% correct
Looks like D to me
Technically, the stretching is done before the translation. Otherwise the coordinates of the vertex would also be scaled.
