Find the instantaneous rate of change of the function f(x) = 6x\" at x = 2' Start with the formula for the instantaneous rate of change calculation. Then, approximate the limit by using small value of h, then even smaller and smaller values of h. Your approximation of the instantaneous rate should be precise to the three decimal places. The instantaneous rate of change for the function at x = 2 is (Round to three decimal places as needed)
