Question

Given f(x) = the quantity of 4x plus 1, divided by 3, solve for f-1(3).

Answer 1

\[f(x) =\dfrac{4x+1}{3}\]
right? I guide and you work, deal??

Answer 2

yup! so the answer would be 13/3

Answer 3

f(1)=3, f(0)=2 and f(-1)=1
These can be proved by putting the respective values of x in f(x).
Do you get my point?

Answer 4

Confirm: what do you mean by f-1(3)?? is it \(f^-(3)\)

Answer 5

my bad?

Answer 6

ok ok

Answer 7

wut?

Answer 8

nah its cool

Answer 9

well I have 1 more question after this!

Answer 10

ok, @emmii2239 now,
1/ switch the role of f(x) and x on the expression above, what do you have?
I mean if you see x, then replace by f-(x) , if you see f(x) , then replace by x
show me what you get??

Answer 11

I dont get what youre saying
