\n" ); document.write( "\n" ); document.write( "Yes, it would be a function if you consider that a negative function value is nonsensical, hence it makes sense to restrict the range. The type of function is predicated on which of the several possible choices you make for the independent variable.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you want to solve for it is an exponential function. If you want to solve for , except for very odd circumstances where , this would be a polynomial function. If you know the period interest rate, that is , then calculating is an exponential function also.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you are solving for either A or P for a fixed period, rate, and number of compounding periods so that the exponential part becomes a constant, then you have a linear function.\r
