Do exponential functions only model phenomena that grow, or can they also model phenomena that decay? Explain what is different in the form of the function in each case.
\n" ); document.write( "-------------------------------
\n" ); document.write( "Exponential Form: y = ab^x
\n" ); document.write( "If b>1 the function is a growth function
\n" ); document.write( "Ex: y = 2*3^x
\n" ); document.write( "--------------------
\n" ); document.write( "If 0 < b < 1 the function is a decay function
\n" ); document.write( "Ex y = 2*(1/3)^x
\n" ); document.write( "-----------------------
