Question

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

Answer 1

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

Explanation:

I took the EDGE test and it was correct

Answer 2

`f(x)=2x+1\to y=2x+1\\\\\text{We solve for x}\\\\2x+1=y\ \ \ |-1\\\\2x=y-1\ \ \ |:2\\\\x=(y-1)/(2)\to x=(1)/(2)y-(1)/(2)`

`\text{Answer:}\ f^(-1)(x)=(1)/(2)x-(1)/(2)`
