2, Error Analysis Abi said the inverse of
f(x) = 3x + 1 is f-1(x) = 3x - 1. Is she correct?
Explain.

No

Step-by-step explanation:

To obtain the inverse function

let y = f(x) and rearrange making x the subject, that is

y = 3x + 1 ( subtract 1 from both sides )

y - 1 = 3x ( divide both sides by 3 )

= x

Change y back into terms of x, thus

(x) =

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
