The derivative of a function of f at z is given by f' (x) = lim f(Ith)-f(1) h+0 h provided the limit exists. Use the definition of the derivative to find the derivative of f (x) = 6x2 + 5x + 2. Enter the fully simplified expression for f (x + h) - f (x). Do not factor. Make sure there is a space between variables. f ( z + h) - f (I) = f' (I) = Show your work and explain, in your own words, how you arrived at your answers. 50 XX Equation A - A- Ix BIUSX X Styles Font Size Words: 0
