Question

inverse function of x-3/1+4x

Answer 1

oh my
a lot of algebra

Answer 2

you have to solve
\[x=\frac{y-3}{1+4y}\] for \(y\)

Answer 3

you know how to do that?

Answer 4

no i keep getting stuck when i get to x+4xy= y-3 im not sure what to switch

Answer 5

\[
x+4xy= y-3 \\
x + 3 + 4xy = y \\
x + 3 = y - 4xy = y(1 - 4x) \\
\frac{x+3}{1-4x} = y \\
y = \frac{x+3}{1-4x}
\]

Answer 6

thanks
