A is correct

- metalslayer

But is the given graph translated 4 units left? I thought a was right until I saw that

- Plasmataco

It would still have a v shape

- metalslayer

I just need to know if I did a - e correctly. I believe c is correct. I am confused on what difference is a and b.

- metalslayer

But is the graph translated 4 units left or not?

- Plasmataco

It's just it won't have to be on the y axis

- Plasmataco

The diference is that A's graph can be moved from left the right but B's graph moves up and down

- Plasmataco

They are still the same

- Plasmataco

Shape

- metalslayer

Great, and is the given graph translated left, or is it at 0,0. Because I put all of my graphs at 0,0.

- Plasmataco

Yes.

do I move the second graph 4 units up or 4 units down?

- Plasmataco

For B, u can move both up and down. For A u can move both left and right

- Plasmataco

Think of A as horizontal and think of B as vertical

- metalslayer

I understand that, but do I move graph B up or down because the parent function is translated left. I left: up or down?

- metalslayer

Wait, I think I got it. The graph is translated 2 units up, so I get it now

- metalslayer

I think?

- metalslayer

Is C correct? and is d and and e correct?

- Plasmataco

Hang on

How do u upload image?

- metalslayer

Use desmos and a screen shot. Or take a photo and use attach file. And you can also use the draw button.

Sry, on an Ipad

I know it's a rough sketch. But is this an inverse? If yes, then C is correct. I believe D and E are wrong though

- Plasmataco

Yes c is correct. I'm investigating the equation of the graph

- metalslayer

The graph looks like a sin graph but it has been dilated, translated, etc

- Plasmataco

The graph equation is 4sin(10/pi*x-2)-2

- metalslayer

What should I do for D? Should I dilate it by 2?

- metalslayer

And is graph E a compression?

- Plasmataco

Sry, I meant 4sin(5x/pi-2)-2

- Plasmataco

D makes the highest point 2 times taller and the lowest point 2 times lower maintaining the same center and shape

- Plasmataco

And E makes the farthest point to the right farther from the center and the farthest point to hit left 2 times farther. The domain becomes from -8 to 16 instead of -4 to.8

- Plasmataco

I'm not too sure about a and b

- Plasmataco

D and e are wrong tho.

- Plasmataco

Sry couldn't help as much

- metalslayer

Anyone else with good help? Btw, thanks Plasmataco

- Loser66

Open a new one, please

- metalslayer

Ok, will do.

- metalslayer

I will include new graphs, (improved)
