Algebra-2

To represent a vertical stretch of by a factor of 3, followed by a reflection across the x-axis, we need to apply the transformations step by step:

Vertical stretch by a factor of 3: This means multiplying the function by 3, which stretches the graph vertically.

Reflection across the x-axis: This means multiplying the function by to flip the graph across the x-axis.

Thus, applying both transformations to
