Question

writing the inverse of a function
complete the steps in order to write the inverse of ( f(x) = x + 5 )
1 (square = x + 5)
2 (square = y + 5)
3 (square = y)
4 (square = x - 5)

Explanation:

Step1: Replace $f(x)$ with $y$

$y = x + 5$

Step2: Swap $x$ and $y$

$x = y + 5$

Step3: Isolate the term with $y$

$x - 5 = y$

Step4: Replace $y$ with $f^{-1}(x)$

$f^{-1}(x) = x - 5$

Answer:

1. $y$
2. $x$
3. $x - 5$
4. $f^{-1}(x)$
