Thread: function defined

For the function defined by f(x)=2-x^2, 0 less than or equal to x, use a sketch to help find a formula for f^-1(x). Gave this one my best shot but I need some help with this one. my answer is: f^-1(x)= squrt2-x, x less than or equal to 2.

You have,
for
It inverse (interchange x and y),

Thus,

Thus,

Thus,

Below is the graph,
(red is the original function
gree in the inverse,
balck is the identity function showing the symettry)

Hacker, may I ask what software do you use to create your graphs?

I'm sort-of scared to click on something that claims to be a trojan horse, a download, and one of those "swat-the-fly" ads.

Trojan: Is any malicious code/program which discuses as an innconect program like, ( Yazzle Sodoku Game ), while is spyware/malware/adware/dailer/keylogger/backdoor,...
Thus, how can that possibly be a trojan! If it claims to be one. Just click it (we have a policy here on MHF that more malware is allowed).

I am not so sure I like the policy makers

Oops, I did not releaize what I wrote.
I wanted to write,
"No malware is allowed", I guess it was a natural instinct for me to write that.

thanks for checking my answer.
