You can put this solution on YOUR website! The following function is one to one find its inverse.Find the domain and range of
f and f^-1
f(x)=3x+1/4
**
y=3x+1/4
To find the inverse, interchange x and y, then solve for y.
x=3y+1/4
3y=x-1/4
y=x/3-1/12
f^-1=x/3-1/12
..
Both f and f^-1 are equations for straight lines which mean there are no restrictions, that is,
domain and range for both are all real numbers or (-∞,∞) in interval notation.
