The correct description of the end behavior of the function \( y = \log x \) is:
As \( x \to 0^+ \), \( y \to -\infty \), and as \( x \to \infty \), \( y \to \infty \).
So the associated response is:
As x right arrow 0 superscript positive baseline , y right arrow negative infinity , and as x right arrow infinity , y right arrow infinity .
