Question

@callisto.

Answer 1

Sorry...:( I'm back....

Answer 2

Is this correct?

Answer 3

We start with the graph: y = cos(θ)
 Horizontal compression by factor of ½.
 Horizontal translation of 22.5 units left
 Vertical stretch by factor of 3. y = 3cos(x)
 Reflection in the x-axis. y = -3cos(3x)
 Vertical translation 3 up.

Answer 4

@experimentX is super clever and smart!!!

Answer 5

So with that order, and with expressing the graph, I answered this correctly right?

Answer 6

Once again
We start with the graph: y = cos(θ)
 Horizontal compression by factor of ½. y=cos2x
 Horizontal translation of 45 units left. y=cos(2x+45)
 Vertical stretch by factor of 3. y = 3cos(2x+45)
 Reflection in the x-axis. y = -3cos(2x+45)
 Vertical translation 3 up. y= -3cos(2x+45)+3

Answer 7

lol. I know. I mean with your order

Answer 8

With the order you gave me, that would be good right?

Answer 9

Hmm.. I hope so. only in my opinion only :(

Answer 10

Wait, you made changes to it?

Answer 11

yes :P

Answer 12

So instead of 22.5 its 45?

Answer 13

I think so...

Answer 14

Ok. Got it. Thank you @callisto!

Answer 15

Hmm I didn't explain anything though

Answer 16

One of the most important things is the order of the transformations, If i didnt fix that, I would have gotten less marks. Thank you

Answer 17

I don't even know if my answer is correct. Most probably, I would get wrong from transformation of graphs. Lack of practice
