Please show work and explain answer thank you

The tollowing is Mobius' explanation for a solution to this question. You can use this and other online reterenoes as a guide, but your explanation should be in your own words. The derivative of a function of f at m is given by f, (m) = lim f(w+h)f(w) h>0 h provided the limit exists. Use the definition of the derivative to find the derivative of f (11:) = 3:1:2 + 7:: + 7. Enter the fully simplified expression for f (:1: + h) f (:5). Do not factor. Make sure there is a space between variables. f(m+h)f(w)= :Im M: :1m
