y=b^x
\n" ); document.write( "48=ab^2
\n" ); document.write( "750=ab^5
\n" ); document.write( "divide the last by the middle
\n" ); document.write( "750/48=b^3=15.625
\n" ); document.write( "b=cube root of 15.625=2.5
\n" ); document.write( "a2.5^2=48
\n" ); document.write( "6.25a=48
\n" ); document.write( "a=7.68
\n" ); document.write( "7.68*(2.5^5)=750.
\n" ); document.write( "The function is f(x)=7.68(2.5)^x
