Consider the family of functions f(x) = 9x+ A sin(x) where A is a constant. Note: A is an uppercase letter. (a) Determine f'(x) = (b) Determine the minimum value of f'(x). Your answer may contain a. minimum value of f'(x) is: (c) Determine conditions on A so that f is always increasing. Write your result in interval notation. Hint: use the result of part (a) AND the fact that f'(x) needs to be non-negative. f is always increasing for A in the interval(s):
