Question

9. Match the description to its equation: moves right 7

A. y = x² + 7
B. y = (x+7)²
C. y = x²-7
D. y = (x-7)²

Answer 1

Answer is D. ( x -7)^2

Reason = x - 7 is to the right, x + 7 is to the left
If you have ( x - 7 ) = 0,
Add 7 to both sides and you get
x -7 +7 = 0 + 7
Or
x = +7
I hope this makes sense
