The function is stretched vertically by a factor of 2
The function is compressed horizontally by a factor of 1/3
The graph is reflected into the x-axis
The graph translates 2 units to the left
The graph translates downwards 5 units
IS THAT CORRECT?
The function y = x becomes y= -2(3x+2)-5. Describe the order in which the transformations would take place.

The function is compressed horizontally by a factor of 1/3 (or stretched vertically by 3)
y = 3 x
Translates 2 units up
y = 3x+2
reflects over x axis
y = -(3x+2)
stretch vertically by 2
y = -2(3x+2)
down 5
y = 3 x
Translates 2 units up
y = 3x+2
reflects over x axis
y = -(3x+2)
stretch vertically by 2
y = -2(3x+2)
down 5
