For questions #6-10, use the shortcuts for derivatives that we developed in class. No limit processes necessary! Simplify each answer in a way that is consistent with how the function is given. (Leave it the way you found it.) 6. Given at f (x) =4x' -3x' +17x-12, find at f'(x) . . Given at f (x) =(4x3 -3)(2x +1), find at f'(x). 8. 12.x Given at f (x) = 4x2 2, find at f'(x). 9. Given at f (x) =5x3 --, find at f'(x). 10. Given at f (x) =4 x' -127/x , find at f'(x)
