The coordinates for y = f(x) is (-1, 0), (0, 3), (1, 0), (2, -3), (3, 0). Give the new coordinates of y = -f(½(x+2)).

Let me try:

Original coordinates (-1, 0), (0, 3), (1, 0), (2, -3), (3, 0)

-f(x) (-1, 0), (0, -3), (1, 0), (2, 3), (3, 0)

f(½x) (-2, 0), (0, -3), (2, 0), (4, 3), (6, 0)

f(x+2) (-4, 0), (-2, -3), (0, 0), (2, 3), (4, 0)

New coordinates for y = -f(½(x+2)) is (-4, 0), (-2, -3), (0, 0), (2, 3), (4, 0).

Is this right??
