Question

Let f(x) = 5x + 12. Find f-1(x).

Answer 1

Is that inverse?

Answer 2

To find the inverse:

Replace f(x) with y
Switch x's and y's, so put x where y is and x where y is.
Solve for y
Replace y with f^-1(x)


please try this yourself for now.

Answer 3

i forgot alot of things

Answer 4

its been awhile

Answer 5

Just try man, I don't judge if you get anything wrong, I'll be honest, I see people who say this all the time, it just requires like a minute or two of some effort :\.

alright thank you

Answer 7

Yeah no worries

Answer 8

Did you do any of it yet?

Answer 9

\[f(x) = 5x+12\]

Answer 10

\[y = 5x+12\]

Answer 11

\[x=5y+12\]

Answer 12

\[y = \frac{ x-12 }{ 5 }\]

Answer 13

\[f ^{-1}(x) = \frac{ x-12 }{ 5 }\]
