Algebra.Com's Answer #734663 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Q65... \n" ); document.write( "When x increases by 1 (from 1 to 2) the value of f(x) decreases by a factor of 3^2 = 9; i.e., it gets multiplied by a factor of 3^-2. That means k=2. \n" ); document.write( "Then for x=1 we have \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The function is \n" ); document.write( "f(x) = 81(3^(-2x)) \n" ); document.write( "Q66... \n" ); document.write( "Your statement of the question is not clear.... \n" ); document.write( " |
