What is the inverse of the function f(x) = 2x + 1?

The inverse = f-1(x) = (x - 1)/2.

Step-by-step explanation:

f(x) = 2x + 1

2x = f(x) - 1

x = (f(x) - 1)/2

Now replacing the x by the inverse f-1(x) and the f(x) by x, we get:

f-1(x) = (x - 1)/2.

Step-by-step explanation:

f(x) = 2x + 1change f(x) to y

y = 2x + 1now switch ur x and y

x = 2y + 1...now solve for y

x - 1 = 2y ...divide both sides by 2

(x - 1) / 2 = yrearrange

y = (x - 1) / 2 OR y = x/2 - 1/2 <
