First, I'll assume you meant 15 + 2*log x.
Unlike the TI83 and TI84 calculators, the TI92 (and TI89) don't
automatically include parentheses after function names. Try entering
15+2*log(x). The asterisk for multiplication may not be required (I haven't
used my 92 in a while), but I'm sure the parentheses ARE required.
