&- Choose a composite square root function of the form g(f(x)) where the function g is a square root function and f is any polynomial function more complicated than V = ax, aER. Note: An example of an appropriate composite square root mction would be g(x) = 2:: 3. However, you must pick a function other than this example for this task. L Show the step-by-step computation of the correct derivative of 90:) using the chain rule. L Using the function 9 you constructed for part A, nd the instantaneous rate of change at x = 0.123
