Question 483402
Find the inverse of the function g(x)= 2x-1
**
y=2x-1
The procedure for finding the inverse is to interchange x and y, then solve for y:
x=2y-1
2y=x+1
y=(x+1)/2  (this is the inverse of 2x-1)
see graph below as a visual check on the answer: (red line is first equation, green line, the inverse)
