To determine if a graph represents a function, the vertical line test is used; if any vertical line intersects the graph at more than one point, the graph does not represent a function. To check if a function is one-to-one, which means each x-value maps to a unique y-value and vice versa, the horizontal line test is applied; if any horizontal line intersects the graph more than once, the function is not one-to-one.
