Best ResponseYou've already chosen the best response.0What is the correct order of the functions from least to greatest according to the average rate of change on the interval from x = 1 to x = 3?

Best ResponseYou've already chosen the best response.0the rate of change of that line is a constant it is the slope do you know it?

Best ResponseYou've already chosen the best response.0@satellite73 Would 0.5/3 be the slope? I'm pretty bad at this, haha

Astrophysics

Best ResponseYou've already chosen the best response.1You have to find the slope of each function f(x), g(x), and h(x) \[A(x)= \frac{ f(b)f(a) }{ ba }\] this is the average rate of change dw:1440377631421:dw

Best ResponseYou've already chosen the best response.1So what is f(3) for f(x)?

Best ResponseYou've already chosen the best response.0f(3)=((3)+3)^22, am I doing okay, so far?

Xaze

Best ResponseYou've already chosen the best response.0f(3)=(9)^22  > f(3)=812 > 79?

Best ResponseYou've already chosen the best response.1Not quite, 3+3 = 6 :P

Best ResponseYou've already chosen the best response.0Oh whoops... I was thinking of multiplication, for some reason.. f(3)=(6)^22 > f(3)=362  > f(3)=34?

Best ResponseYou've already chosen the best response.1@satellite73 hey if you want to take an image and upload it on draw which is very useful check out this guide on how to do it http://openstudy.com/users/astrophysics#/updates/55921cb5e4b0c2028eab5952 it's really quick to get it and helpful :P

Best ResponseYou've already chosen the best response.1perfect now we have \[f(x) = \frac{ 342 }{ 3(1) }\]

Best ResponseYou've already chosen the best response.1Yup m = 8 for f(x)

Best ResponseYou've already chosen the best response.1We're doing g(x) now

Best ResponseYou've already chosen the best response.0Computer is slowing down  sorry, sorry xx The two points are (1,2) and (3,0)

Astrophysics

Best ResponseYou've already chosen the best response.1Yup perfect, so use \[m = \frac{ y_2y_1 }{ x_2x_1 }\] to find the slope dw:1440378607899:dw this is what it means visually

Xaze

Best ResponseYou've already chosen the best response.0All right... dw:1440382384897:dw

Best ResponseYou've already chosen the best response.1So we have slope for f(x) = 8, g(x) = 1/2, now lets find the slope for h(x)

Xaze

Best ResponseYou've already chosen the best response.0Not sure how to find the slope for that one... doesn't seem to be in my notes

Best ResponseYou've already chosen the best response.1Just read the table and apply the formula

Best ResponseYou've already chosen the best response.0The formula \[m=y2y1/x2x1\]? Just making sure

Xaze

Best ResponseYou've already chosen the best response.0Okay, before I solve, how did you know to get (1,14) and (3,62) from the chart? Or did you pick them randomly... and any pair you choose would give the same slope?

Astrophysics

Best ResponseYou've already chosen the best response.1No, because your question is asking for the average rate of change from x = 1 to x = 3, but it doesn't really matter, you'll get the same slope for any two points

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.1Yes! Now we have the slopes f(x) = 8, g(x) = 1/2 and h(x) = 12 now put it least to greatest and we're done
