Gabby was asked by her teacher to list the transformations of the quadratic function f(x) = 2(x + 3)2 – 5 when compared to the parent function f(x) = x2. Which of her answers were correct? I. Vertical stretch of 2

II. Horizontal shift right 3

III. Vertical shift down 5

IV. Reflection across the x-axis.

Group of answer choices

a) I and III

b) I and II

c) II and III

d) II and IV

i believe that the answer is

b. y-1=-2(x-4)

hope this !

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
