Answer 2

to find the inverse of a function, swap f(x) and x,
and then solve for f(x)

Answer 3

if you start with
\[ f(x)= \frac{1}{2x+3} \]
first rename f(x) to "x" and x to "y"
\[ x= \frac{1}{2y+3} \]
and then you solve for "y" ?
one way is to first "flip" both sides to get
\[ \frac{1}{x}= 2y+3 \]
or
\[ 2y + 3 = \frac{1}{x} \]
what is the next step ?

Answer 4

to figure out y?
