Question

See attached!!!

Answer 1

Well I'll give you a clue. Amplitude=Height of wave.

Answer 2

I know the answer has to be B or C.

Answer 3

Mmmmm... What makes you think that

Answer 4

hint : see the value of y for x=2

Answer 5

Is this a cosine graph?

Answer 6

y= d+a sin(bx-c)
y= d+a cos (bx-c)

amplitude =a. The vertical stretching or shrinking if your wave.

Answer 7

Look up cosine and sine graphs on google and you will see which one yours is.

Answer 8

also use shubham hint

Answer 9

It looks more like a cosine graph....

Answer 10

I disagree.. Also because you aren't looking at your amplitude.

Answer 11

yeah and he is done with amplitude when he said answer is between B and C

Answer 12

Its D!!! Right?

Answer 13

That's what I think it is... But sassy pants seems to disagree.

Answer 14

Who disagrees?

Answer 15

@ganeshie8

Answer 16

Amplitude = (high - low) / 2
= (4--2) /2
= 6/2
= 3

Answer 17

D is the first option to remove from ur possible answers

Answer 18

cuz, oly A B and C have amplitudes of 3

Answer 19

I was always taught that amplitude is simply absolute value of a.

Answer 20

It's c

Answer 21

here the graph is shifted up by 1 unit

Answer 22

yes !

Answer 23

Who's been teaching me -_-

Answer 24

Checking height at x=2 would have been sufficient to cross-check any option .

Answer 25

So wait whats the right answer?

Answer 26

yes that uniquely tells C is the correct equation

Answer 27

What??

Answer 28

how do you that it is shifted one to the left? how did u get 3?
