Question

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

Answer 1

Answer:

The first choice $hx = \frac{1}{2}x - \frac{1}{2}$

Step-by-step explanation:

Inverse functions are when you switch the y and x

btw f(x) is the same as y

y = 2x + 1

becomes

x = 2y + 1

solve it :)

subtract 1 from both sides

x - 1 = 2y

divide 2 from both sides

$\frac{x-1}{2}$

same as

$\frac{1}{2}x - \frac{1}{2}$

so ya know it's the first choice
