on Find an equation for the function f(x) whose derivative is f'(x) = 4sin(8x) and whose graph passes TT through the point 8 Select one: O a. b. d. 1 f(x) = - cos(2x) +2 16 c. f(x)= e. f(x) = 1 -cos(16x) +4 1 f(x) = - 1 f(x) = cos(8x)+1 cos(8x)-1 1 X cos(8x) +8 Incorrect

2. Find the derivative of each function: cos (x) 1-x² (b) g(x) = 5³√x - (a) f(x): (c) f(x) = (3x² + x − 12)(7x² − 4x) - (d) s(t) = 2t³ - 8t+4

Please help me with this question.
