Which function is the inverse of f(x)=2x+3

MAXImum [283]

Answer:

$f^{-1}(x)=\frac{x-3}{2}$

Step-by-step explanation:

we have

$f(x)=2x+3$

Let

$y=f(x)$

$y=2x+3$

Exchanges the variables x for y and y for x

$x=2y+3$

Isolate the variable y

$2y=x-3$

$y=\frac{x-3}{2}$

Let

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

$f^{-1}(x)=\frac{x-3}{2}$
