B) No

Question

Quizplus · Accepted Answer

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 $f(x) = \sqrt{x - 2}$ passes the horizontal line test, meaning no horizontal line intersects the graph of the function at more than one point. This indicates that the function is one-to-one.
