Final answer:

The fourth derivative of the function f(x) = 4x^4 - 4x^3 + 5x^2 + 3x - 7 is 96, a constant, indicating no further changes in curvature after this derivative.

Step-by-step explanation:

To find the fourth derivative of the function f(x) = 4x⁴ - 4x³ + 5x² + 3x - 7, we must differentiate the function four times with respect to x.

First derivative:
f'(x) = 16x³ - 12x² + 10x + 3

Second derivative:
f''(x) = 48x² - 24x + 10

Third derivative:
f'''(x) = 96x - 24

Fourth derivative:
f''''(x) = 96

The fourth derivative is a constant, which shows that the rate of change of the curvature has stabilized and no further changes in curvature occur after the fourth derivative.
