-0.087 3) Find the instantaneous rate of change of the function H(t)=80+110e when t= 6. 4) Given that f(4)= 3 and f'(4)=-5, find g'(4) for: a) g(x) = V«f(x) b) g(x)= f(x) = X 5) If g(2)=3 and g'(2)=-4, find f'(2) for the following: a) f(x)= x² – 4g(x) b) f(x)= (g(x)) c) f(x)=xsin (g(x)) d) f(x)=x* In(g(x))
