i think it shifts down 2 units and reflects the x-axis..

i think

it shifts down 2 units ....Incorrect

and

reflects the x-axis..Correct

Multiplication by a positive factor (>1) implies stretch. Here it is stretching in the vertical axis.

thanks, keep getting those numbers outside the function of x mixed up..
