The correct answer is:
• The magnitude of the estimated average rate of change of the exponential function over the interval [-9, 2] is less than the magnitude of the estimated average rate of change of f (x) over the interval [-9, 2].
• The estimated average rate of change of the exponential function over the interval [-9, 2] is negative, while the estimated average rate of change of f (x) over the interval [-9, 2] is positive.
• The magnitude of the estimated average rate of change of the exponential function over the interval [-9, 2] is less than the magnitude of the estimated average rate of change of f (x) over the interval [-9, 2].
• The estimated average rate of change of both the exponential function and f (x) over the interval [-9, 2] is approximately 1.5.
• The magnitude of the estimated average rate of change of the exponential function over the interval [-9, 2] is greater than the magnitude of the estimated average rate of change of f (x) over the interval [-9, 2].
• The magnitude of the estimated average rate of change of the exponential function over the interval [-9, 2] is less than the magnitude of the estimated average rate of change of f (x) over the interval [-9, 2].
