Consider the function f(x) whose second derivative is f''(x) = 7x - 8sin(x) if f(0) = 2 and f'(0) = 4, what is f(x)?
a. 7x² - 8cos(x) + C, where C is the constant of integration.
b. x² - 8sin(x) + 4x + C, where C is the constant of integration.
c. x² - 8cos(x) + 4x + C, where C is the constant of integration.
d. 7x² - 8sin(x) + 4x + C, where C is the constant of integration.
