Let f be the function given by f(x) = 3 sin x + 8e. What is the value of f'(0) *f prime*)

Question

Let f be the function given by f(x) = 3 sin x + 8e. What is the value of f'(0) *f prime*)

A) 3

B)5

C)8

D)11

Answer 1

so let's take the derivative of the function:

f(x)=3sinx+8e, f'(x)=3cosx (8e is a constant so it's derivative is 0)

f'(0)=3cos(0)=3*1=3 (A)
