The following Is Moblus' explanation for a solution to this question. You can use this and other online references as a guide, but your explanation should be In your own words. The derivative of a function of f at I is given by f' (z) = lim f(Ith)-f(I) h +0 h provided the limit exists. Use the definition of the derivative to find the derivative of f (x) = 712 + 2x+9. 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 (x) = f (z) = 14x+2 Show your work and explain, In your own words, how you arrived at your answers.
