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

AyeEEEEEEEEEEEEE @DanJS

hi

5. DanJS

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

6. DanJS

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

8. DanJS

good?

9. DanJS

is this for calculus 1, or physics.. or

Alg 2

-,-

12. DanJS

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

13. DanJS

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

I forgot the formula

its -2 i think

16. DanJS

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

okay i got -2

18. DanJS

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

Did that

20. DanJS

looks good

OHH

THANKS MAN I LOVE YOU

23. DanJS

ha, you get er now?

YEA

25. DanJS

kk, goodluck

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
