Use the given information to find f'(2). g(2) = 2 and g'(2) = -5 h (2) = -1 and h'(2) = 3 f (x ) = 9(x) h (x ) f ' ( 2 ) =The percent P of defective parts produced by a new employee If days after the employee starts work can be modeled by f + 1790 p = . 70(t + 2) Find the rates of change of P at t = 1 and t = 10. (Round your answers to two decimal places.) (a) t=1 (b) 1': 10 3= x percent/day
