1. (1 point) Find the most general antiderivative of f (x) = 6 +4x2 513. Note: Any arbitrary constants used must be an upper-case '90,?- F (I) = 2. (1 point) Find the most general antiderivative of f(x) = 4 + 6%. Note: Any arbitrary constants used must be an upper-case '90,?- F(x) = 3. (1 point) 1 4 7 Find the most general antiderivative of u) = z'. Note: Any arbitrary constants used must be an upper-case 99C!!- F (u) = 4. (1 point) Let 1%.) = 5 +1x4/5. (a) Find the most general formula for f\" (x). If an arbitrary constant must be used here, use an uppercase \"C\". x) = (b) Based on your answer to (a), nd the most general for- mula for f (x). If another new arbitrary constant must be used here, use an upper-case \"D\". f(x) =
