Question

Let f(x) = 7x - 13. Find f-1(x)

Answer 1

\(\bf f(x)={\color{red}{ y}} = 7{\color{blue}{ x}} - 13\qquad inverse\implies {\color{blue}{ x}= 7{\color{red}{ y}}} - 13 \iff f^{-1}(x)\)

as you can see, all we do is firstly swap about the variables
then just solve for "y"

Answer 2

then ?

Answer 3

then, that'd be the inverse function

Answer 4

so whats the answers

Answer 5
