Answer 1

Do you mean f(-1)?

Answer 2

\[f^{-1}(x)\]

Answer 3

lolol

Answer 4

=(x-7)/12

Answer 5

-f(x) maybe :P

Answer 6

lmao f(x)^-1 :P

Answer 7

or is that a negative prime? :o

Answer 8

= \[\LARGE {1 \over 12x + 7}\]

Answer 9

12

Answer 20

dy/dx = 12

Answer 21

medal please

Answer 22

12x^1 +7(x^0) --> 12 + 0

Answer 23

f'(x) = 12

Answer 24

medal please, one for me one for you :D

Answer 25

My options are

x+12/7
x-7/12
x+7/12

Answer 26

you haven't answered the question asked tai

Answer 27

\[f(x) = 12x + 7\]\[f(x)-7=12x\]\[\frac{f(x)-7}{12}=x\]\[\frac{x-7}{12}=f^{-1}(x)\]
