Answer:
7. y = f(x +2) -7
8. y = -f(x -5)
9. y = f(-x) +3
Step-by-step explanation:
The general transformation can be written ...
y = a·f(b·(x -c)) +d
'a' is the vertical expansion factor. A negative value means the graph is reflected over the x-axis.
'b' is the horizontal compression factor. A negative value means the graph is reflected over the y-axis.
'c' is the number of units of right-shift.
'd' is the number of units of up-shift.
__
7. 2 left and 7 down means (c, d) = (-2, -7), so the transformed function is ...
y = f(x +2) -7
__
8. reflected over x and 5 right means (a, c) = (-1, 5), so the transformed function is ...
y = -f(x -5)
__
9. reflected over y and up 3 means (b, d) = (-1, 3), so the transformed function is ...
y = f(-x) +3
_____
The graph shows an asymmetrical function that makes it possible to tell what the transformations are. The original is dashed orange. The various y-values correspond to the problem numbers. You can see that the transformations match the problem statements.
