Answer 2

What do you think?

Answer 3

hmm hld on sec

Answer 4

x is either right (+) or left (-)
y is either up(+) or down(-)

Answer 5

Look at f(x) first.

Answer 6

i'm thinking D

Answer 7

Is g(x) in the left or right side of f(x)?

Answer 8

Look at the vertex.

Answer 9

its on the right side

Answer 10

Right? :O

Answer 11

That's the f(x), not g(x)

Answer 12

oo then the left

Answer 13

up left

Answer 14

So the f(x) should move to the left, right? Because g(x) is in the left.

Answer 15

yea

Answer 16

This means it is -. so (x-???)

Answer 17

How many units in the left? will you move the vertex of f(x) to the g(x)?

Answer 18

x-5

Answer 19

Count again.

Answer 20

ahh 4

Answer 21

so B

Answer 22

Great! :)
