The image contains a graph of two functions, one represented by a solid line and the other by a dashed line. The question is asking whether these functions are inverses of each other, focusing on logarithmic and exponential functions.

Explanation:

The functions appear to represent an exponential function and its inverse, a logarithmic function. The inverse of an exponential function is a logarithmic function, and vice versa. Inverse functions reflect over the line $y = x$, meaning that if you reflect the exponential function over this line, it should result in the logarithmic function.

Analyzing the choices:

• A. Incorrect. Inverse functions do not need to have their intercepts align in any particular way except that they reflect over the line $y = x$.

• B. Correct. The key property of inverse functions is that reflecting one over the line $y = x$ results in the other. This matches the description of exponential and logarithmic functions being inverses.

• C. Incorrect. This reasoning is not related to inverse functions. The position relative to the x-axis does not determine if functions are inverses.

• D. Incorrect. The fact that neither passes through the origin does not determine whether the functions are inverses.

Correct Answer:

B. The functions are inverses because reflecting the function with a solid line across the line $y = x$ results in the function with a dashed line.
