Question

Which of the following is the vertex of y=−f(−x)
if the original function has a vertex of (−9,−8)
?(1 point)

(−9,8)


(−9,−8)


(9,−8)


(9,8)

Answer 1

Start with (x, y) = (−9, −8).

f(−x) reflects across the y-axis → vertex at (9, −8).
Then −f(−x) reflects across the x-axis → vertex at (9, 8).

Answer: (9, 8).
