Document Summary

F ( x)=bx ,b >0,b 1 is a positive constant if x=n,bn=a a a a>0 x=0, b0=1 x= n ,b n= 1 bn >0 domain: { x: 1 : increasing function, if 0 < b < 1 : decreasing function. Whenever y=f (x) ,then f 1( y)=x f must be one to one on the domain to ensure an inverse on that domain. Never take on the same value twice. *horizontal line test-> no horizontal line intersects its graph more than once. Log function: f ( x)=logb ,b>0, b 1 b=e, f ( x)=lnx=loge. * logb bx=x ,x r blogb x=x, x>0 log rules: Loga x= lnx lna logc x logcb if logb x. Demand-> quantity q" of opads" that will be bought at price p" a. ) estimate that when p=, weekly d=5000 units, for every increase weekly d decreases by 50 units.
