If f(x) = x^2 - 1, find f(3).
5
2
8
-2

- Notamathgenius

\[F(3)= x ^{2} \]-1

- Notamathgenius

Ok that came out Totally wrong, you need to find F so really take all the numbers plu gin for F and get your answer.

- Notamathgenius

Plug

- anonymous

i have no idea .-. none of them were equal to eachother when i plugged numbers in

- Notamathgenius

Oh I am sorry, I meant X not F :P wow I deserve a slap to the face -_-

- anonymous

noooo :c

- Notamathgenius

It's 3 -_- how stupid of me :P

- anonymous

how would i find out F though? i cant find out what x is unless i know what f(3) is all together.

- Notamathgenius

Unless they give you F (they wont most of the time) It is 1 so 3x1=3 .

- anonymous

so the answer is?

- Notamathgenius

-2 :D

- anonymous

yay!
