Determine whether or not the situation describes a function. Give a reason for your answer.The letter grade in this course is a function of your numerical grade.

A relation is a function when each input has exactly one output. Here, the numerical grade is the input, and each numerical grade is assigned one letter grade. Different numerical grades may receive the same letter grade, but that does not prevent it from being a function. The correct choice is “Yes, it is a function. Each numerical grade corresponds to one letter grade.”
