For the function f(x)=(3x)/(x+2)
a. find the average rate of change from x=2 to x=5
b. find the derivative f'(x) from first principles, by setting up the difference quotient, (f(x+h)-f(x))/(h) and finding lim h->0 (f(x+h)-f(x))/(h)
c. use part b to find the rate of change of f(x) at x=2© BrainMass Inc. brainmass.com March 4, 2021, 8:24 pm ad1c9bdddf
The average rate of change is determined. the derivatives for the instant rate of change is found. Step by step solution provided.
