Okey

OpenStudy (jenniferjuice):

okey...?

OpenStudy (broskishelleh):

Did you make an equation?

OpenStudy (broskishelleh):

Well the rule is: \[[f(4) - f(7)]\div7 - 4\]

OpenStudy (broskishelleh):

I'll use f(x)=2(x-9)^2+17 as the equation y2=2(7−9)^2+17 y1=2(4−9)^2+17

OpenStudy (broskishelleh):

y1 = 4 y2= 7

OpenStudy (broskishelleh):

y1 = 67 y2 = 25 So 67 - 25 = 42/3

OpenStudy (broskishelleh):
