Question

Help PLEASE - if this is the graph of f(x)=a^(x+h) +k then .... (answers on the attachment along with graph)

Answer 1

ok with this one i have absolutely no idea what this means .... lol ANYONE .... help

Answer 2

Answer 3

graphed it n_n

Answer 4

now can you see that -10 tells us the y-displacement.

Answer 5

So if the graph comes down, k should be negative.

Get this?

Answer 6

yesss getting it n_n so k is y coordinate

Answer 7

meaning up or down

Answer 8

Not the y-cordinate to be exact. But yes, the "y-change/movement/displacement.

Answer 9

oh okkkkkkk then

Answer 10

Now try guessing the value of h.

Answer 11

h would be the y-change, right?

Answer 12

if so then around -3 to -4

Answer 13

h would be the change on the x-axis.
Try drawing th e graph of 2^x and then compare.

Answer 14

ok i guess h would be around 5 or 6 ... @saifoo.khan

Answer 15

Try again.
Hint: Because of h > 0 (i.e. h = 5), the graph moved to the left side.

Answer 16

would it be a Negative number then ?

Answer 17

ohhhh would the answer to the question question be D h>0 and k<0 n_n - since k is -3 or -4 its less than zero??

Answer 18

No.

^^ In this graph, the graph is moving to the RIGHT.

Answer 19

ohhhhh my bad im getting the graphs mix LOL ---

Answer 20

;)

Answer 21

im sorry im heading no where @saifoo.khan im really bad with math

Answer 22

would the answer be A h<0 and k>0 ???

Answer 23

k is like -10 in this case.
h is the opposite of 5 in 2^(x+5) - 10 problem.

Answer 24

Try reading the whole thread again. Don't rush.

Answer 25

ok thank you i will defitinely go over it

Answer 26

Knock me if you still don't understand it. (:

Answer 27

ok thank you n_n @saifoo.khan !

Answer 28

hello im sorry to bother you again.... BUT i gave up lol i dont really know what im doing --- this is what i have -> k will be negative because its going down around -3 or -4 ...... h would be positive because the graph is going to the right and it looks like x would be 5 or 6 ----- other than that im at a Dead End :( i dont really know what i am suppose to look for ??? @saifoo.khan

Answer 29

idk why but i always end up with answer D

Answer 30

That's all you need... why is the question still open...?

Answer 31

When:
h - negative - right.
h - positive - left.
It's the opposite actually.

Answer 32

oh ok

Answer 33

because i have come to no conclusion... @agent0smith

Answer 34

k is negative?
Now just tell me where is your graph going? Left or right?

Answer 35

right...

Answer 36

So h should be negative.

Answer 37

ok so far then both k and h are negative ...

Answer 38

meaning both would be less than zero

Answer 39

Yes, sir.

Answer 40

ohhhh soooo its B n_n

Answer 41

Yes, sir.

Answer 42

omgoshhhhhhhhh i am in great depth to you thank you n_n! @saifoo.khan

Answer 43

How deep?

Answer 44

lol

Answer 45

;)

Answer 46

Oh yeah it is reversed here. Normally the equation uses x-h not x+h.

When it's x-h, positive h means it goes right. Negative h means left. They messed with convention here.
