You can put this solution on YOUR website!
f(x) = ba^x + c
\n" ); document.write( "y = ba^x - 2
\n" ); document.write( "y = ba^x - 2 P(0,2)
\n" ); document.write( "2 = ba^0 - 2
\n" ); document.write( "2 = b - 2
\n" ); document.write( "4 = b
\n" ); document.write( "plug.:
\n" ); document.write( "y = 4*a^x - 2 P(1,4)
\n" ); document.write( "4 = 4*a - 2
\n" ); document.write( "6 = 4a
\n" ); document.write( "3/2 = a
\n" ); document.write( "plug.:
\n" ); document.write( "f(x) = 4(3/2)^x - 2
