Reagan, a teacher's assistant, is grading quizzes. The function f(x) gives the number of quizzes she can grade in x minutes. What does f(30) = 15 tell you? Choices: (A)Reagan can grade 30 quizzes in 15 minutes. (B)Reagan can grade 15 quizzes in 30 minutes.

Function Representation: The function f(x) represents the number of quizzes Reagan can grade in x minutes. The function value f(30) = 15 means that when we input 30 minutes into the function, the output is 15 quizzes. This tells us how many quizzes Reagan can grade in 30 minutes, not the other way around.Interpreting f(30) = 15: To interpret f(30) = 15 correctly, we need to understand that the input x = 30 represents the time in minutes, and the output f(x) = 15 represents the number of quizzes graded. Therefore, f(30) = 15 means Reagan can grade 15 quizzes in 30 minutes.
