Answer:
A. y=-f(x-3)
Explanation:
The new graph is the original graph translated 3 to the right and flipped downwards.
To apply this to the equation y=f(x) add a negative sign because the new graph is negative so y= - f(x)
The graph moves 3 to the right so put -3 inside the brackets. The new equation is y= -f(x-3)
