@zepdrix I'm so sorry to annoy you once more but if you could kindly help me, I would deeply appreciate it

OpenStudy (maggy14145):

HELLO I SEE U

OpenStudy (unklerhaukus):

What is the value of the first function at x=7? and at x=3?

OpenStudy (maggy14145):

Please help i need answers ASAP

OpenStudy (maggy14145):

50, 10

OpenStudy (unklerhaukus):

so the function has changed by the amount 50 - 10 while x has changed an amount 7 - 3 The average rate of change has been (50-10) / (7-3) (simplify this)

OpenStudy (maggy14145):

40/4=10

OpenStudy (unklerhaukus):

good so for the first function we've got 10 now do the same for the second functon

OpenStudy (maggy14145):

ok give me a sec

OpenStudy (maggy14145):

um it doesn't have exact points

OpenStudy (maggy14145):

I need help like ASAP I need to submit this assignment before 12

OpenStudy (unklerhaukus):

they look close enough to exact

OpenStudy (unklerhaukus):

rememeber we don't actually need the perfect numbers, we are just looking for the function with the greatest rate of change

OpenStudy (maggy14145):

so (3,9)

OpenStudy (unklerhaukus):

the second function look like 1 at the point x=7

OpenStudy (maggy14145):

and (0,6)

OpenStudy (maggy14145):

please. I need help ASAP

OpenStudy (unklerhaukus):

and 9 at x = 3

OpenStudy (unklerhaukus):

so 1-9 / 7-3

OpenStudy (maggy14145):

-8/4=-2

OpenStudy (unklerhaukus):

yes -2.

OpenStudy (maggy14145):

that looks like its out of the picture

OpenStudy (unklerhaukus):

negative is fine, it mean the function has gone down

OpenStudy (unklerhaukus):

ready for the third function?

OpenStudy (maggy14145):

yea no i meant like as far as correct answers goes, its not the qualified option I'm looking for

OpenStudy (maggy14145):

yes

OpenStudy (unklerhaukus):

oh right, yeah its -2 is less than 10

OpenStudy (maggy14145):

ok so for dis one lets see what it is

OpenStudy (maggy14145):

(0, 25)

OpenStudy (maggy14145):

please is there anyway this can go faster. or if u already know that its the first one I'd appreciate if you'd tell me. I have a few more I need to finish up and this is taking forever

OpenStudy (unklerhaukus):

the method is the same

OpenStudy (unklerhaukus):

you know how to compute the average over some interval

OpenStudy (unklerhaukus):

the correct answer is the function with the greatest rate of change

OpenStudy (maggy14145):

well yes I am aware of that

OpenStudy (unklerhaukus):

What are the rates of change from x=3 to 7 on the third and fourth functions ?

OpenStudy (maggy14145):

the last one is (3,0) and (5,0)

OpenStudy (unklerhaukus):

i don't think so

OpenStudy (maggy14145):

ugh I'm not quite sure
