Question 1039152
{{{graph(300,200,-10,10,-10,10,6x-2,(x+2)/6)}}}
This passes the horizontal and vertical line tests and is one-to-one.
To do the inverse of a function, change the x and y, and if there is an inverse, it will be symmetric around the y=x line. You can reflect the function across the 45 degree line and can see that in the graph.
For a function f(x)=6x-2
y=6x-2
now change the x and y
x=6y-2
Solve for y
x+2=6y
divide by 6
(x+2)/6=y
The inverse is
x=6y-2
y=(x+2)/6
The range of the first function is infinite and so is the domain of the second.
The range of the second function is also infinite, and so is its domain.
