Many-One Relation Function and Its Inverse Function

**SengNee** · March 13th 2008, 06:56 PM

$f(x)=(x+2)^2-3$
$g(x)=(x-3)^2+5$
$h(x)=(x+5)^2+1$

Find the inverse function of each function above and sketch both funtion and inverse function.

(Please show me all answers of the 3 function I given, you no have to worry about I have no exercise to try, because I have a lot of exercise books. Thanks a lot.)

I still don't understand.......

Inverse function
Should give a better understanding in that table.

Still don't understand...

The restriction should x≥0?
Or
Let, stationary point=(a,b)
The restriction should x≥a?

If the inverse function is square root of y, we should assume square root of y are always ≥0?
