Question

Find the derivative of the function.  = 3 sin x + 9x - 9
A) 3 cos x + 9 
B) -3 sin x + 9 
C) -3 cos x + 9 
D) 3 sin x + 9

Quizplus · Accepted Answer

The derivative of 3sin(x) is 3cos(x) and the derivative of 9x is 9. The derivative of a constant (in this case, -9) is 0, so it can be ignored. Therefore, the final derivative is 3cos(x) + 9.
