4

Step-by-step explanation:

y = -(x + 1)² + 1

Shift 1 unit to the right:

y = -(x + 1 − 1)² + 1

y = -x² + 1

Shift 5 units down:

y = -x² + 1 − 5

y = -x² − 4

Rotate 180° about the vertex:

y = -(-x²) − 4

y = x² − 4

Find the zeros:

0 = x² − 4

x² = 4

x = -2 or 2

Therefore, a = -2 and b = 2, so b−a = 4.
