The average rate of change of the function between x = 15 to x = 25 is ___degrees Celsius per thousand feet and represents the rate of change of temperature per thousand feet.

OpenStudy (anonymous):

altitude in ft. (x) temprature (in c) f(x) 15 4 20 -6 25 -16 30 -26

OpenStudy (anonymous):

i think its -6 or 20

OpenStudy (johnweldon1993):

Rate of change... so temp/altitude -16 - 4 ------- = ? 25 - 15

OpenStudy (anonymous):

-20 over 10

OpenStudy (johnweldon1993):

Which simplifies to...

OpenStudy (anonymous):

-2

Looks correct to me
