Answer:
10. f'(x) = (x/14) + (14/9)
11. f'(x) = - x + 2
12. f'(x) = 2x - 8
Step-by-step explanation:
The step to solving inverse is a simple trick. You must invert x and y.
For (10.) let f(x) = y
then y = 9x - 14
x = 9y - 14 (this is inverting x and y)
solving for y: x + 14 = 9y
therefore : y = (x/14) + (14/9)
You can do this for the others as well and using simple "solve for x" methods, you can solve for y which is f'(x).
