Which graph represents a function whose domain is the set of nonnegative real numbers?
The domain is the set of xvalues used in the construction of the graph.
Nonnegative xvalues would start at x = 0 and move to the right. A function can be determined with the vertical line test. That is, if a vertical line is passed through the graph and it hits in more than one point, it is not a function. In other words, each xvalue can match up with only one other yvalue. A.) is a function whose domain consists of both positive and negative real numbers. B.) Is not a function D.) is a function whose domain consists of negative real numbers and zero C.) is a function whose domain is the set of nonnegative real numbers.
