What is the average rate of change of f(x), represented by the table of values, over the interval [-3,4]

Average rate of change = 3

Step-by-step explanation:

here   a = -3 and b = 4

⇒ Average rate of change = f(b) - f(a)  / b - a

                                            = (27 - 6) / (4 - (-3))

                                            = 21 / 7

                                            = 3

Therefore, Average rate of change = 3

i believe the answer is c.
