Question

Three logarithmic functions are graphed on a coordinate grid.Three logarithmic functions are graphed on a coordinate grid. All are increasing and pass through the point left-parenthesis 1 comma 0 right-parenthesis. Between x equals 0 and x equals 1, the curve labeled c is on top, the curve labeled b is in the middle and the curve labeled a is on the bottom. For all x-values greater than 1, the curve labeled a is on top, the curve labeled b is in the middle, and the curve labeled c is on the bottom.

To match the logarithmic functions to the curves based on the given characteristics:

1. **Behavior between \( x = 0 \) and \( x = 1 \)**:
- Curve \( c \) is on top, followed by curve \( b \), and curve \( a \) is at the bottom.
- Since logarithmic functions increase less steeply for larger bases, the highest logarithmic function (most increasing) between \( 0 \) and \( 1 \) will correspond to the smallest base, which is \( \log_2(x) \). Therefore, curve \( c \) corresponds to \( h(x) = \log_2(x) \).

2. **Behavior for \( x > 1 \)**:
- Here, curve \( a \) is on top, followed by curve \( b \), and curve \( c \) is at the bottom.
- As \( x \) increases, logarithmic functions with larger bases grow faster. Thus, the curve that is at the top in this region will correspond to the largest base, which is \( \log_7(x) \). Consequently, curve \( a \) matches with \( f(x) = \log_7(x) \).
- This leaves the middle curve, \( b \), which corresponds to \( g(x) = \log_3(x) \).

Given this reasoning, we can summarize the matches as follows:

- Curve \( a \): \( f(x) = \log_7(x) \)
- Curve \( b \): \( g(x) = \log_3(x) \)
- Curve \( c \): \( h(x) = \log_2(x) \)

Thus, the correct response is:

**a. \( f(x) = \log_7(x) \), b. \( g(x) = \log_3(x) \), c. \( h(x) = \log_2(x) \)**.
