Which function is the inverse of f(x) = 2x+3?
or(x) = -x-
F(x) = x -
r1(x) = –2x+3
or(x) = 2x + 3

Solution:

Given function is:

f(x) = 2x + 3

We have to find the inverse of f(x)

The inverse of a function is writing x  in terms of  y

Let,

y = f(x)

Then,

y = 2x + 3

Exchanges the variables x for y and y for x

Isolate the variable y, which means keep "y" alone in left side of equation

Therefore, inverse of function is:
