Question

if f(x)= 6x-9

what is f of f (-1)

Answer 1

f(-1)=6(-1)-9
f(-1)=-6-9
so f(-1)=-15

Answer 2

hey can you help me with some similar problems please

Answer 3

yeah:)

Answer 4

What is the problem Breno?

Answer 5

if f(x)= 1/x
what is f of f(x)

Answer 6

Same thing,

f(x)=6x-9
f(1/x)= 6(1/x)-9
f(1/x)= (6/1)(1/x)-9

f(1/x)= (6/x)-9 ^.^

Answer 7

I think I confuse your question, lol, sorry...
Ok, so if f(x)= 1/x
what is f of f(x)= -x

Answer 8

huh

Answer 9

f(x) = 1/x
f(f(x)) = f(1/x) = 1/(1/x) = x

Answer 10

Correct.

Answer 11

thanks

Answer 12

wlcm

Answer 13

Given that f(x)=|x| and g(x)=2x−3
what is f of g(x)

Answer 14

f(g(x)) = f(2x - 3) = |2x - 3|

Answer 15

i got it nvm

Answer 16

You mean f = |x|, what is f(f(x))?
