I need help with 3,6,9,12, and 15! Thank you

1-6 Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] Then find the derivative dy/dx. 1. y = V1 + 4x 2. y = (2x3 + 5)4 3. y = tan TX 4. y = sin(cot x) 5. y = vsin x 6. y = sin Vx 7-46 Find the derivative of the function. 7. F(x) = (5x6 + 2x3)4 8. F(x) = (1 + x+ x2) 99 9. f(x) = 15x + 1 10. g(x) = (2 - sin x) 3/2 1 1 11. A(t) = 12. f(x) (cost + tan t) 2 3 x2 - 1 13. f(0) = cos(02) 14. g(0) = cos3 0 15. h(v) = 03/1 + 02 16. f(t) = t sin it 17. f(x) = (2x - 3) 4 (x2 + x + 1)5 18. g(x) = (x2 + 1)3 ( x2 + 2) 6 19. h (t) = (t + 1) 2/3 ( 2+2 - 1) 3 20. F(t) = (3t - 1)4(2t + 1)-3 4 3 1 8 21. g(u) = 22. y = x+ us + X 24. U(y) - y + 1 23. y = Vx+1 25. h(0) = tan(02 sin 0) 26. f(t) - 12 +. 4
