Find f'(x) for the given function.

f(x) = 5/3-x

f(f(x)) = 9x - 10

Step-by-step explanation:

Another way to format ff(x) is f(f(x)).

Whenever there is something inside the parentheses, like f(3), you replace x for 3 in the function.

So f(3) = 5 - 9 = -4

Therefore, we can do the same with f(f(x))

f(x) = 5 - 3x

so f(f(x)) is f(5 - 3x).

f(5 - 3x) = 5 - 3(5 - 3x) = 5 - 15 + 9x = 9x -10

f(f(x)) = 9x - 10

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

8.3 and the 3 is repeating

hope this .
