Question

The function f(x) = x2. The graph of g(x) is f(x) translated to the left 6 units and down 5 units. What is the function rule for g(x)?

Answer 1

A. g(x) = (x + 6)2 - 5

B. g(x) = (x - 5)2 + 6

C. g(x) = (x - 6)2 + 5

D. g(x) = (x + 5)2 - 6

Answer 2

@satellite73 last one :)

Answer 3

nope

Answer 4

it would be a right ?

Answer 5

ya

Answer 6

tnx for checking my work! apprciate it

Answer 7

f(x)= x2

(x-b)2+a

a moves it up

b moves it right.

Answer 8

ANNOYING WHEN PEOPLE LIE... thank u @timo86m

Answer 9

@dan815 sry u were wrong

Answer 10

lol

Answer 11

yea soo funny . wasnt asking for a answer was checking if my anser was right no wonder y u have a high score bc u give everyone fake answers LOL @dan815

Answer 12

xD

Answer 13

what was the answer?

Answer 14

i actually did think about it and say A lol

Answer 15

b

Answer 16

Answer 17

was it an online test?

Answer 18

Answer 19

ohh I see! you misunderstood what timo was trying to explain to you

Answer 20

he is talking about the a and b in the equation

Answer 21

your answer is really A, trust me!!

Answer 22

Translated left 6 and down 5. To get this,we take our original equation \(\large f(x)=x^2\) we go LEFT 6,that would be -6. and down 5. We can rewrite this as \[\large g(x)=(x-\color{green}{(-6)})^2 +\color{blue}{(-5)} = (x+6)^2 -5\] Our new vertex will be (-6,-5) for g(x) whereas the vertex of f(x) = (0,0)

Answer 24

Here is your graph of answer b. Does this seem like it's moving LEFT 6 and DOWN 5 to you? http://fooplot.com/plot/eailn8ldt0

Answer 39

don't know. never done it. but only two questions...

Answer 40

hopefully i got enough time xD i just hit the books on fourier series

Answer 41

what is fourier series

Answer 42

you know laplace transforms and that stuff?

Answer 43

fourier series is pretty much the samething, except we use mostly cos and sin graphs to represent a function from what i learnt

Answer 44

nup

Answer 45

its kindd of like a bit of linear algebra

Answer 46

you know how a vector can be represented by any combinations of 3 vectors that are orthogonal to each other

Answer 47

yep

Answer 48

okay well thats the theory, suppose there are orthogonal functions infinite orthogonal functions on a given interval

Answer 49

than any given function can be represented as a sum of these orthogonal functions

Answer 50

and cosnx and sin nx where n goes from -inf to inf are such orthgonal functions

Answer 51

basically fourier series just represents this
