Question

Which function is the inverse of f(x) = -5x - 42

Answer 1

Answer: $\frac{x+42}{-5}$

Step-by-step explanation:

To find the inverse of a function, follow these steps:

First step: Rewrite $f(x)$ as y

$y=-5x-42$

Second step: Swap x and y.

$x=-5y-42$

Third step: Solve for y.

$x+42=-5y\\\frac{x+42}{-5}=y$
