need some help with these

Differentiate the function using one or more of the differentiation rules. y= (7+4x3) 5 y can be represented as a composition of functions f(g(x)), where y = f(u) and u = g(x). Identify the functions g(x) and f(u) that allow y to be written as an expression raised to an exponent. g(x) and f(u) should be chosen such that neither will need to use the chain rule. g (x) = (Type an expression using x as the variable.) ((4 ) = (Type an expression using u as the variable.) y' = 0\fDifferentiate the following function. 8 V= X e dy dx
