Question

CHECK MY ANSWER PLEASE and show steps if incorrect
What would be the translated points,
orginal points of y=f(x),(-6,2),(-3,-4),(0,-4),(3,-4),(6,4) with the new formula being
2y= f(-3x + 6) - 2
i got (4,0),(3,-3),(2,-3),(1,-3),(0,1)

ALSO

for the graph of y=√(16-x^2 )
A) a horizontal compresion by a factor of 1/2
(i got y=4-2x)
B) vertical expansion by 3 and reflected in the y axis
(i got 1/3y=4+x)
