If #f(x) =-sqrt(3x-1) # and #g(x) = (x+3)^3 #, what is #f'(g(x)) #? Calculus Basic Differentiation Rules Chain Rule 1 Answer Leland Adriano Alejandro Jan 16, 2016 #f' (g(x)) =( -9(x+3)^2)/(2 sqrt(3(x+3)^3 -1)# Explanation: #f(x) = -sqrt(3x-1)# and #g(x)=(x+3)^3# #f(g(x)) = -sqrt(3(g(x))-1)# #f(g(x))= -sqrt(3(x+3)^3 -1)# #f' (g(x)) = (-1)*(1/(2 sqrt(3(x+3)^3 -1)))*3*3(x+3)^2*1# #f' (g(x)) =( -9(x+3)^2)/(2 sqrt(3(x+3)^3 -1)# Answer link Related questions What is the Chain Rule for derivatives?
