Answer:
B. The graph is stretched vertically by a factor of 2
Step-by-step explanation:
A non-rigid transformation changes the shape of the curve.
In y + 5 = -2(x - 1)²
- the +5 translates the graph 5 units down (a rigid transformation)
- the -1 translates the graph 1 units to the right (a rigid transformation)
- the -2 vertically stretches the graph by a factor of 2 (a non-rigid transformation) and reflect it across the x-axis (a rigid transformation)
