Answer 2

Are you sure? Show me how you got it plese ;)

Answer 3

all the y values are increased by 4

Answer 6

Ok thanks I might need help with a few more but I'll tag you and become a fan

Answer 7

doesnt it look like the whole line was shifted up by 4 units

Answer 8

Your right

Answer 9

you're*

Answer 10

:)

Answer 11

Which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x) + 4?
The graph shifts 4 units up.

The graph shifts 4 units down.

The graph shifts 4 units left.

The graph shifts 4 units right.

Answer 12

I think its maybe B

Answer 13

its the same thing we just did

Answer 14

k was +4 remember and it made it go up by 4

Answer 15

So it would be A??

Answer 16

yes

Answer 17

Awesome thanks so much

Answer 18

g(x)=f(x)+k
g(x)-f(x)=k
f(x) and g(x) show y coordinates
from graph it'll always 4, so k =4
