Suppose that f is a function given as f(c) = 71 + 6. We will compute the derivative of fat = = 5 as follows. First, we will compute and simplify the expression f(5 + h). f (5 + h) = Then we compute and simplify the difference quotient between > = 5 and z - 5 + h . f(5 + h) - f(5) h The derivative of the function at $ = 5 is the limit of the difference quotient as h approaches zero. f'(5) =lim f (5 + h) - f(5) h 10 h
