Question

Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?

O -2(x - 2)2 = -8(7 + y)
O yx2-
o yo hx²-x-6
y=-2+ 28+4x
O y=2+28+4x

Answer 1

-2(x - 2)2 = -8(7 + y)

Explanation:

2(x - 2)2 = 8(7 + y)

(2x - 4)2 = 56 + y

4x - 8 = 56 + y

4x - 8 - 56 = y

4x - 64 = y

If option A

-2(x - 2)2 = -8(7 + y)

(-2x + 4)2 = - 56 - y

- 4x + 8 = - 56 - y

- 4x + 8 + 56 = - y

- 4x + 64 = - y

4x - 64 = y

(RIGHT)✔

Answer 2

-2(x-2)2=-8(7+y)

Explanation:

• Inverse means just -

Lets solve afterwards

`\\ \sf\longmapsto -2(x-2)2=-8(7+y)`

`\\ \sf\longmapsto (-2x+4)2=-56-y`

`\\ \sf\longmapsto -4x+8=-56-y`

`\\ \sf\longmapsto -4x+y=-64`

`\\ \sf\longmapsto 4x-y=64`
