**rate of change for f(x)**
f(x)=-0.3x^2
-0.3(1)^2=-0.3^2=-0.09
-0.03(5)2=-0.15^2=-0.0225
rate of change = (-0.0225-(-0.09))/(5-1)=0.0675/4=0.016875
f(x) rate of change is 0.016875 or about 0.02
**rate of change for g(x)**
g(x)=-0.6x^2
-0.06(1)^2=-0.06^2=-0.0036
-0.06(5)^2=-0.3^2=-0.09
rate of change = (-0.09-(-0.0036))/(5-1)=-0.0864/4=-0.0216
g(x) rate of change is -0.0216 or about -0.02
**how much greater?**
0.02(-1)=-0.02
g(x) is -1 times of f(x)
