Question

what steps would i take to find the inverse of :
f(x)=22x+3

Answer 1

\(\bf f(x)={\color{blue}{ y}}=22{\color{red}{ x}}+3\qquad inverse \implies {\color{red}{ x}}=22{\color{blue}{ y}}+3\)

notice, to get the "inverse relationship" what you'd do is just swap about the variables
then solve for "y"

Answer 2

Well an inverse is essentially putting y in for x in the equation. f(x) is basically y=. So y=22x+3 turns into x=22x+3.
The graphs are also flipped over the line y=x.

Answer 3

No, x=22y+3. You don't have to subtract the +3, all you have to do is put y in for x.

Answer 4

ohh my i see
i was thought i was way more complicated xD

Answer 5

thanks
