Answer 11

@whpalmer4 can you help me? i was thinking a , or B

Answer 12

Let's go through the answers one by one.

"It is decreasing in the interval \(2 < x < 4\)"

That is only partly true. From \(x = 2 \text{ to } x=3\), the \(y\) value of the graph (which represents the velocity at time \(x\)) is indeed decreasing, which shows decreasing velocity. However, what happens from \(x=3 \text { to } x=4\)? The \(y\) value increases, so velocity is increasing, and the statement above is not true. Scratch A.

Answer 13

The second answer choice is

"It is decreasing in the interval \(3 < x < 4\)"

Uh, problem author, weren't you paying attention? We just demonstrated that it is increasing in that very interval, and that's why A wasn't a correct answer choice. Turns out B isn't a correct answer choice, either, and we didn't have to do any more work to determine that :-)

Answer 14

Now, hopefully that gives you enough information to make the correct choice between C and D.

Answer 15

C ? >.<

Answer 16

wow :0

Answer 17

Tell me why you choose C.

Answer 18

(don't now change your answer to D because I asked that question — I would ask that question regardless of which choice you make!)

Answer 19

No actually i do want to change my answer to D.

Answer 20

you said " However, what happens from x=3 to x=4? The y value increases, so velocity is increasing,"

Answer 21

u could have just said d

Answer 22

but he wanted me to explain lol

Answer 23

Okay, d is a good choice :-)

Here's a hint: explaining something to someone else is a good way to solidify your understanding. That's why I ask people to do that when they choose an answer.

Answer 24

So D, is right? Thank you!

Answer 25

Yes, D is correct. Overall, the velocity is constant from x = 0 to x = 2. Then it decreases from x = 2 to x = 3, increases from x = 3 to x = 4, and is once again constant from x = 4 to x=6. At that point, the person walks into a lamp post and falls to the ground, unconscious :-)

Answer 26

Sometimes you have to read between the lines a bit, but I'm pretty sure that's what happens at x = 6 :-)
