are the following functions inverse?
If not, rewrite the 2nd function so that it is an inverse of the 1st.
f(x)=3x+1
Find the inverse, y = f(x)
y = 3x + 1
or
3x + 1 = y
Swap y for x and solve for y:
3y + 1 = x
3y = x - 1; subtract 1 from both sides
y = ; divided both sides by 3
(x) =

g(x)=3x-1/3; obviously this is not the inverse of,
