To fin the inverse first replace \(f(x) \rightarrow y\) Switch \(y\) and \(x\) Solve for \(y\) Relabel it \(g(x)\)

Alright, you've found your inverse, now you're looking for \(f(g(x))\) and \(g(f(x))\)
anonymous
  • anonymous
so would i use (fog) or (gof)
Jhannybean
  • Jhannybean
Yep
anonymous
  • anonymous
which one woudl i use?
Jhannybean
  • Jhannybean
\[f(g(x)) = f\left(4x-8\right) =\frac{1}{4}(4x-8)+2 =~?\] \[g(f(x)) = g\left(\frac{1}{4}x+2\right) =4\left(\frac{1}{4}x+2\right)+2=~? \]

  • anonymous
ok so do it wiht both of them irhgt?
Jhannybean
  • Jhannybean
Yep, we're proving their inverses of one another.
anonymous
  • anonymous
okie thanks :)

Let's work both of them out.
anonymous
  • anonymous
ok
Jhannybean
  • Jhannybean
\[f(g(x)) = f\left(4x-8\right) =\frac{1}{4}(4x-8)+2 =\frac{1}{4}(4x) - \frac{1}{4}(8)+2 = x-2+2 = \color{red}{x}\]
anonymous
  • anonymous
i already got that i just need help on the (gof)(x) one
Jhannybean
  • Jhannybean
\[g(f(x)) = g\left(\frac{1}{4}x+2\right) =4\left(\frac{1}{4}x+2\right)\color{blue}{-8} =4\left(\frac{1}{4}x\right) +4(2)\color{blue}{-8} = x \color{red}{+8-8} = x\]
Jhannybean
  • Jhannybean
It was a typo. I was looking at \(f(x)\) and wrote in a \(+2\) instead of a \(-8\) .
anonymous
  • anonymous
oh ok thanks
