Remember, you've
got two ways you can double-check this answer to see if it's
right:
| |
 |
Graph |
 |
and |
 |
on the same graph
and |
| |
|
see
if they're mirror images over the line
y =
x.
(Easy -- since these are both lines.) |
Do it!
*Note:
This is just like
( f
o g
)( x
),
but with different notation.
OK, here's the list of
steps:
| How to find
the inverse of a function:
STEP 1:
Stick a "y" in for the "f(x)."
STEP 2:
Switch the
x
and
y.
STEP 3:
Solve for
y.
| |
STEP 4:
Stick |
 |
in
for the "y." |
THEN, CHECK IT! |
