Algebra.Com's Answer #122662 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The function f(x)=|x+3|+9 is NOT a one-to-one function. The points (19,31) and (__,__) prove that f is not a one-to-one function. What is the missing set of points? \n" ); document.write( "------------------- \n" ); document.write( "Solve y = |19+3}+9 \n" ); document.write( "y = 31 \n" ); document.write( "---------- \n" ); document.write( "Solve 31 = |x+3|+9 \n" ); document.write( "22 = |x+3| \n" ); document.write( "x+3 = 22 or x+3 = -22 \n" ); document.write( "x = 19 or x = -25 \n" ); document.write( "----------------------- \n" ); document.write( "So two of the solution pairs are (19,31) and (-25,31) \n" ); document.write( "This shows that f is not one-to-one. \n" ); document.write( "=================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
