Mathematics

The relation shown in the 2nd diagram is a function.  The reason for this is that one and only one y-value is associated with each x-value.  

Note that this is not true of the first diagram.  If x=0, there are two separate y vaues associated: -1 and 2.  This clearly states that the first diagram does not represent a function.

Of the provided graphs, the second would be the correct answer.

Functions occur when the input only has one possible output (though the output can be recieved through multiple inputs)

Veronika [31]

Answer:

The slope of f(x) is greater than g(x). In fact, it is double the slope of g(x). This means Reena can make envelopes two times as fast as Greg. But the y-intercept of g(x) is greater than f(x), meaning at 0 minutes, Greg starts with more envelopes than Reena. If they work for 20 minutes, Greg will have 10 more envelopes than Reena. But if they work longer than 30 minutes, Reena will have a larger stock of envelopes than Greg.
