Question

What is the average rate of change from x = −3 to x = 5?

Answer 1

I guess that depends on how long it took to get from -3 to 5

Answer 2

8?

Answer 3

choices
−1

0

1

8

Answer 4

You need more information. What is y when x is -3? What is y when x is 5?

Answer 5

well yes the difference between them is 8, so i'd go with 8

Answer 6

but the question is asked in a very weird way, because there isn't really a 'rate of change'.

Answer 7

I think your missing some information. There has to be a place hold value for x = -3 and x = 5

Answer 8

Well, rate of change is slope, so, if this is a line in on the x-axis slope would be zero. And if there is change in y-coordinates it would be m=(x-x1)/(y-y1)

Answer 9

^ you don't have your y ._.

Answer 10

Right??

Answer 11

No.. >.> pretty sure its not like that

Answer 12

\[\left| -3+5 \right|=8\]

Answer 13

I'm sure rate of change is slope. 100% sure.

Answer 14

yes but you need to know y or t or something for a slope

Answer 15

Yup, the rate of change is the slope!

Answer 16

Exactly what I said ._.

Answer 17

Right so where is y?

Answer 18

\[\frac{ \Delta y }{ \Delta x }\]

Answer 19

No, @JTsoccer, where is y in your question?

Answer 20

What?? x = −3 TO x = 5

I don't get it, ( ._.)

You must have been giving some other kind of information..

Answer 21

Is there a graph with this question, or coordinates, or values for y or t?

Answer 22

I'd say slope is zero for that problem since why is not given and it's assumed the line is on the x-axis.

Answer 23

@JTsoccer

Answer 24

typo, why = y.. lol

Answer 25

From what I see it, you get the value of of x = -3 and x = -5 and plug them into f(b) - f(a) /b - a

Answer 26

There is no rate of change between two lines.

Answer 27

Without @JTsoccer were going no where here. Peace ~ :3

Answer 28

@tHe_FiZiCx99 yeah lol
