Question

f(x)=x+6/5. find f^-1(6).

the answer is 12/5, correct?

Answer 1

i got 24/5

Answer 2

thats not one of the possibilities...

Answer 3

the answer is one of these:
12/5
5/12
36
-24
24

Answer 4

is f(x) = x + (6/5) or is it (x+6)/5

Answer 5

the second

Answer 6

then its 24

Answer 7

why

Answer 8

To find the inverse of f(x), swap the x and y and solve for y
\[f(x) = \frac{x+6}{5}\]
so \[f^{-1} = 5x - 6\]
plug in 6 to get 30-6 = 24

Answer 9

how did u get 5x-6?

Answer 10

To find the inverse of f(x), swap the x and y and solve for y

Answer 11

u said that already -_-

Answer 12

ie \[x = \frac{y+6}{5}\]

Answer 13

I know, but that was the answer to your question
