    Find the derivative of f (x) = 7 at x = 3

    Solution

    f(3) space space space space space space space space space space space space space space space equals space limit as h rightwards arrow 0 of fraction numerator f left parenthesis 3 plus h right parenthesis minus left parenthesis 3 right parenthesis over denominator h end fraction equals limit as h rightwards arrow 0 of fraction numerator 7 minus 7 over denominator h end fraction equals limit as h rightwards arrow 0 of 0 equals 0
