1. Problem Description
The point is on the graph of . Given the transformation , we need to find the corresponding point on the graph of .
2. Solution Steps
Let be the corresponding point on the graph of .
We are given . This transformation involves a horizontal shift, a vertical stretch/compression, and a vertical shift.
The argument inside the function indicates a horizontal shift to the left by 6 units. Thus, , which means .
The coefficient in front of indicates a vertical compression by a factor of
3. The term $-3$ indicates a vertical shift downward by 3 units. Therefore, $y' = \frac{1}{3}f(x'+6) - 3 = \frac{1}{3}f(-5+6) - 3 = \frac{1}{3}f(1) - 3$.
Since is on the graph of , we have .
Therefore, .
So the corresponding point on the graph of is .
