Question

Which of the following points lies on the graph of the inverse of f(x) = 6x + 1?
(-1, 0)
(-1, 1)
(1, -1)

Answer 1

first of all you must find the inverse function

to do this you let f(x)=y

y=6x+1

you want to make x the subject



this will be your inverse function, now you know that this is the inverse for f(x)
so you have f^-1(x)=

replace the y with x

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


next you want to substitute the values of x
if it lies on the graph i think it equals 0

Answer 2

Okay thank you that's a lot of help
