Function y= f(-x) is the result of a reflection over the y-axis, therefore the answer would be the graph B.
Function y= - f( x - 1) is the result of a reflection over the x-axis and a translation 1 unit to the right. Therefore the graph would be graph A.
Function y= -f(x) is the result of a reflection over the x-axis. Therefore the graph would be the graph F.
Function y= f(-x) + 3 is the result of a reflection over the y-axis and a translation 3 units up. Therefore the graph would be the graph D.
Function y= -f(-x) is the result of a reflection over the y-axis and a reflection over the x-axis. Therefore the graph would be the graph C.
Function y = -2 - f(x) is the result of a reflection over the x-axis and a translation 2 units down. Therefore the graph would be graph E.
