Question

Graphing help?

Answer 1

Which of the following statements best describes the person's velocity?

It is decreasing in the interval 2 < x < 4.

It is decreasing in the interval 3 < x < 4.

It is increasing in the interval 2 < x < 4.

It is increasing in the interval 3 < x < 4.

Answer 2

I think the answer is A.

Answer 3

(BTW, this is my last question :))

Answer 4

Answer 5

I need help with dilation

Answer 6

Answer 7

what is the graph doing between 2 and 4 ? It does down and then back up

Answer 8

I think when they say decreasing between 2 and 4, they mean it only decreases, none of this down and back up

Answer 9

Oh sorry

Answer 10

This is the beginning:

The graph below shows the velocity of a person (y), in km/h, at a certain time (x), in hours.

Answer 11

Thank you so much you've been a huge help :)

Answer 12

can you pick the correct answer ?

Answer 13

I picked " It is decreasing in the interval 2 < x < 4." Is that the correct answer? Since the change is between points 2 and 4 and it decreases.

Answer 14

But it said the answer was incorrect.

Answer 15

the graph is of the y points. at x=2 y is 4 and at x=3 y is 3 y went down. then y goes back up.

so y is not decreasing between x=2 and x = 4 (it goes down then back up)

Answer 16

Oh

Answer 17

between x=2 and 4 y is not decreasing (only) or increasing (only) so I would ignore those choices.
at x=3, y is 3, and at x=4 y is 4. y increased

Answer 18

** y goes down to 2

Answer 19

Oh

Answer 20

so I meant
at x=3, y is 2, and at x=4 y is 4. y increased

Answer 21

Ohh I get it. Thanks for clearing that up :)
