Question

The inverse of the function y = 4x - 1 is y= x-1/4
true or false

Answer 1

In order to find the inverse of a function you find the y in function of x. So all you have to do is to solve for x in this case.

See if it matches with the answer.

Answer 2

I'm sorry, the x in function of y :).
Solve for x.

Answer 3

\[x=4y-1\]
\[x+1=4y\]
\[y=(x+1)/4\]
which is the same as \[y=x/4+1/4\]
so your answer is false.

Answer 4

You switch the x's and y's and then solve for y. Its basically the same thing alfie said - just a different way of looking at it.
