Question

What is an equation for the inverse of the relation y=4x+2?

Answer 1

this says
1) multiply by 4
2) add 2

inverse will say
1) subtract 2
2) divide by 4
so it will be
\[y^{-1}=\frac{x-2}{4}\]

Answer 2

just like if you were asked to solve
\[4x+2=14\] you would subtract 2 and divide by 4 to get
\[x=3\]

Answer 3

Where did you get the the y^-1 after you did the inverse?
