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

(9, 8)

Explanation: y = -f(-x) reflects the graph of f across the y-axis (x → -x) and then across the x-axis (y → -y). So (-9, -8) → (9, 8).
