Answer:
- The function is vertically scaled (expanded) by a factor of 2.
- The scaled function is translated left 3 units and down 7 units.
Step-by-step explanation:
When a function f(x) is transformed by ...
g(x) = a·f(x -h) +k
it has been vertically scaled by a factor of "a" and translated to the right and up by amounts h and k, respectively.
Here, we have a=2, h=-3, and k=-7. The means ...
The function has been vertically expanded by a factor of 2, translated left 3 units, and translated down 7 units.
