Answer 1

y = F(x) = 3x-3

y = 3x-3

thats the given function, ok

Answer 2

you familiar wid steps of finding inverse ?

Answer 3

its the opposite right?

Answer 4

hmm kindof yes :)

y= 3x-3
you solve x first

Answer 5

isnt it 3?

Answer 6

i mean, solve x in terms of y

y= 3x-3

add 3 both sides
y= 3x-3
+ 3 +3

Answer 7

that gives u,

y+3 = 3x

Answer 8

next, divide 3 both sides ?

y+3 = 3x
/3 /3

\(\large \frac{(y+3)}{3} = x\)

Answer 9

so we have solved x completely eh ?

Answer 10

yes

Answer 11

Next, simply replace x and y

\(\large \frac{(x+3)}{3} = y\)


\(\large y = \frac{(x+3)}{3} \)

Answer 12

thats your inverse of y

\(F^{-1}(y) =\large \frac{(x+3)}{3} \)

Answer 13

oooo ok thank you

Answer 14

np, just remember the two step process of finding inverse... inverses showup all the time... they never leave us :)

Answer 15

ok:)
