absolute change
newer function value- older function value
relative change (percent change)
newer function value-older function value/older function value x 100
average growth rate
newer function value-older function value/newer independent value-older independent value
interpolation
first value+ average growth rate value x number of years
extrapolation
ending value+ average growth rate value x years
inflation (number not percent)
new$= (old$)(1+r)
linear function
(y2-y1)/(x2-x1)=slope, then solve for b
exponential function
y=mx+b
magnitude of earthquake
log(relative intensity)
relative intensity of an earthquake
10^(magnitude)
