Question

PLEASE HELLP????? the function f(x)=x^2. the graph of g(x) is f(x) translated to the right 3 unites and down 3 units. what is the function rule for g(x)?

Answer 1

@nubeer @agent0smith can anyone help :(

Answer 2

@jim_thompson5910 can you help??

Answer 3

Okay, let's put it like this, first start with f(x):
\[\Large y=x^2\]

Answer 4

okay wait what..

Answer 5

Sorry.... I don't know what's happening....

Answer 6

\[\Large y = x^2\]

Answer 7

crap, LaTeX isn't working hang on...

Answer 8

okay haha.

Answer 9

Okay, might as well make do with what I have -_-

Anyway...

start with

y = x^2
yeah?

Answer 10

If you want to translate up (or down) you manipulate the y-part of the equation.
Say, if I want to translate it 7 units up, it would be
y - 7 = x^2

Get it?

Answer 11

okay yeah kinda haha

Answer 12

so since im going 3 down itd be y-3=x^2??

Answer 13

No.... - (strangely enough) is for going UP
+ is for going down.

Don't ask me why, it's going to take a nauseating geometric explanation... (although go ahead and ask me why if you're really curious ;) )

Answer 14

okay yeah i actually knew that i swear hahaha. im confused cause since ihave to go down 3 AND up 3?? so would i have two different things ? like.... y-3=x^2 and y+3=x^2

Answer 15

It's not down and up, it's down and right, LOL
if it's going right, then you change the x-part, right?
