Answer 1

To determine the correct representation of the graph for \( y = \log_5(x) \), we need to consider the characteristics of logarithmic functions.

1. The domain of \( y = \log_5(x) \) is \( x > 0 \), which means it only exists in the first quadrant and part of the fourth quadrant.
2. The range of \( y = \log_5(x) \) is all real numbers, which indicates it can take any vertical value.
3. As \( x \) approaches 0 from the right, \( y \) approaches negative infinity, creating a vertical asymptote at \( x = 0 \).
4. The graph passes through the point (1, 0), since \( \log_5(1) = 0 \).

Now, let's analyze the options provided:

• Option A: Describes a curve that starts in the second quadrant, crosses the y-axis, and approaches a horizontal asymptote at \( y = 0 \) in quadrant 1. This does not match \( y = \log_5(x) \).

• Option B: This option describes a curve that opens down and to the right, which is not a characteristic of logarithmic functions.

• Option C: This describes a curve that starts in quadrant 1, approaches a vertical asymptote at \( x = 0 \), and crosses the x-axis, which aligns with the behavior of a logarithm.

• Option D: There's no description, so we can't analyze this option.

Based on this analysis, the correct choice showing \( y = \log_5(x) \) is:

C. A graph that opens up to the right, approaches a vertical asymptote at \( x = 0 \) in quadrant 1, crosses the x-axis, and continues to decline slowly in quadrant 4.
