Answer 1

Calculate the average rate of change for the given graph from x = 0 to x = 3 and select the correct answer.

Answer 2

AyeEEEEEEEEEEEEE @DanJS

Answer 3

hi

Answer 4

The rate of change they are talking about is the slope of a secant line connecting those two points on the graph

Answer 5

average rate of change - slope of secant line
Instantaneous rate of change - slope of a tangent line, derivative at f(a)

Answer 6

good?

Answer 7

is this for calculus 1, or physics.. or

Answer 8

Alg 2

Answer 9

-,-

Answer 10

ok, when you see average rate of change, it will mean -- the slope of a line through those two given points...

Answer 11

Do you remember how to calculate the slope in relation to the xy-axis?

Answer 12

I forgot the formula

Answer 13

its -2 i think

Answer 14

Just remember, it is how much vertical change there is (y-direction) per one unit change in the x-direction\

The rise/run thing

Answer 15

okay
i got -2

Answer 16

\[slope= \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 17

Did that

Answer 18

looks good

Answer 19

OHH

Answer 20

THANKS MAN
I LOVE YOU

Answer 21

ha, you get er now?

Answer 22

YEA

Answer 23

kk, goodluck

Answer 24

There ya go, no matter what curve graph there is, if they want the average rate of change, just calculate the slope of the straight line through the two endpoints
