anonymous · Answer

oh sorry, i read it wrong. i thought it said "question in profile pic lol

xapproachesinfinity · Answer

just take the slope?

anonymous · Answer

its ok! @K12Questionz

jamierox4ev3r · Answer

http://prntscr.com/6nzsc8 @xapproachesinfinity there really isn't a set slope on this; there appears to be no clear pattern, looking at this

anonymous · Answer

and @xapproachesinfinity im not sure how :(

jim_thompson5910 · Answer

Average Rate of Change from x = a to x = b

$$\Large m = \frac{f(b) - f(a)}{b-a}$$

I'm using m because this is the slope of the secant line (and the slope of the line through the two points)

xapproachesinfinity · Answer

it does not matter
they are looking for an average rate fro 3 to 13 so just do the slope

xapproachesinfinity · Answer

by the slope i mean what jim just did

jamierox4ev3r · Answer

oh lol okay, generally slope implies a straight line relating points. But anyhow, you're measuring how much the value of x has changed when f(x) equals 3 and when f(x) equals 13

jamierox4ev3r · Answer

but in the end, that's just a wording issue. It doesn't really matter, you're right

xapproachesinfinity · Answer

we are interested in amount on change (mean) btw two point
slope of a curve is about instantaneous  change where we consider the slope at a given point

xapproachesinfinity · Answer

of* for on sorry for the language hehehe

xapproachesinfinity · Answer

so my point is the average rate of change btw two point is the usual slope of the "line"

anonymous · Answer

its okay! @xapproachesinfinity

anonymous · Answer

and kk, so given the info can you please explain the method for finding the rate of change? :)

xapproachesinfinity · Answer

jim has given you all
just find the f(3) f(13)
from the table and evaluate

anonymous · Answer

f(3) = 2 And f(13) = 22

anonymous · Answer

so is it 20? :)

xapproachesinfinity · Answer

20/13-3

anonymous · Answer

20/10 = 2 :)

xapproachesinfinity · Answer

see what jim did above

anonymous · Answer

thank u!!!!!!!!!!!!!!!!!!!!!

kk

xapproachesinfinity · Answer

no problem

anonymous · Answer

do you mind helping with 3 more? :)

xapproachesinfinity · Answer
