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.
