Math Problem Statement
Solution
The problem asks to find the domain and range of the transformed function , given that the domain of is and the range is .
Step 1: Finding the Domain of
- The function applies a horizontal shift of by -7 (due to the ).
- Shifting the domain by -7 gives: [ [-1 - 7, 17 - 7] = [-8, 10] ] So, the domain of is .
Step 2: Finding the Range of
- The transformation includes a vertical stretch by 2 and a downward shift of 7.
- First, multiply the range of by 2: [ 2 \cdot [-4, 8] = [-8, 16] ]
- Then, shift the result downward by 7: [ [-8, 16] - 7 = [-8 - 7, 16 - 7] = [-15, 9] ] So, the range of is .
Final Answer:
- Domain:
- Range:

- How would adding a constant inside the function argument affect its domain?
Tip: When transforming functions, handle horizontal shifts (affecting the domain) separately from vertical shifts and stretches (affecting the range).
