To describe the transformations for the function y = −2∣x∣+ 4:

Vertical Stretch and Reflection:

The coefficient −2 in front of the absolute value causes a vertical stretch by a factor of 2 and reflects the graph over the x-axis (because of the negative sign). So the graph is narrower and reflected over the x-axis.

Vertical Shift:

The +4 outside the absolute valu...
