A function is one-to-one if each x-value corresponds to exactly one y-value and each y-value corresponds to exactly one x-value. The function $f(x) = \frac{7}{x-6}$ is one-to-one because for each x-value, there is a unique y-value, and it passes the horizontal line test, meaning no horizontal line intersects the graph of the function at more than one point.
