Answer
### 1. Right 3, Vertical Stretch by 4, Up 19### 2. Reflection across the x-axis, Vertical Compression by
, Down 25
Explanation
## Step 1: Analyze the first function### The function
can be analyzed by comparing it to the basic quadratic function
. The term
inside the square indicates a horizontal shift to the right by 3 units. The factor 4 outside the square represents a vertical stretch by a factor of 4. Finally, the term +19 indicates a vertical shift upwards by 19 units.## Step 2: Analyze the second function### The function
can be analyzed by comparing it to the basic quadratic function
. The factor
represents a vertical compression by a factor of
and a reflection across the x-axis due to the negative sign. The term -25 indicates a vertical shift downwards by 25 units.
