To describe the transformations of the parent function \( f(x) = \log_3 x \) that result in the function \( g(x) = 13\log_3(x-4) \):
- The multiplier \( 13 \) results in a vertical stretch by the factor of 13.
- The minus \( 4 \) inside the parentheses shifts the graph 4 units to the right.
So the completed sentences are:
The multiplier \( 13 \) results in a vertical stretch by the factor of \( 13 \). The minus \( 4 \) inside the parentheses shifts the graph 4 units to the right.
