Exponential functions f(x) = b^x where b is base, x is exponent f(x) = e^x - special exponential function where e is 2.7 when b>1, the graph passes thru (0,1) bigger the base, the faster it grows when 0<b<1, the graph passes thru (0,1) in decreasing/decent shape Logarithmic funcitons inverse of b^x is logx with base b Fact: y=logx with base b <=> b^y = x eg: log8 = 3 81 = 3^4 => 4=log81 Write logarithms in Exponential form log8 base 2 = 3 => 2^3=8 logp base w = 5 => w^5 = p Write Exponents in log form 4^2 = 16 => 2 = log16 base 4 w=p^k => k=logw base p
