Question

what's the inverse of
f(x)=12x+11

Answer 1

y=12x+11
show this function as x=...

Answer 2

so x-11 over 12?

got the answer with the slope

Answer 4

yes

Answer 5

thank you

Answer 6

so easy: first put f(x)=y
second : y=12x+11 then you need to make x alone in one side :
y-11=12x ==> (y-11)/12=x
at the end you must change the place of x to y
y=(x-11)/12
remember in f(x) we gave number to x from domain but in f(x)inverse we gave number to x from range of f(x)

Answer 7

f inverse(x) = (x-11)/12
