WebSolution: We can use the formula for the derivate of function that is the sum of functions f (x) = f 1 (x) + f 2 (x), f 1 (x) = 10x, f 2 (x) = 4y for the function f 2 (x) = 4y, y is a constant because the argument of f 2 (x) is x so f' 2 (x) = (4y)' = 0. Therefore, the derivative function of f (x) is: f' (x) = 10 + 0 = 10. robert ishee obit
