Comparing the functions f(x) = -2|x| - 7 and g(x) = -10|x| - 7, the vertical stretch factor is 5
since -10 = 5 × (-2). Additionally, there is a vertical shift downward by 7 units in both functions.
So, to summarize:
- The transformation involves a vertical stretch with a scale factor of 5.
- There is also a vertical shift downward by 7 units.
