Just as domain are the x values, range are the y values. To null out any confusion, \"y\" is the same as \"f(x)\" if that is the notation you are using.
\r
\n" ); document.write( "\n" ); document.write( "For each range value -1, 1, 3, and 5, we will have an x value. To find the corresponding x to each y value, we just plug in the range for y, one at a time
\r
\n" ); document.write( "\n" ); document.write( "-1:
\n" ); document.write( "y=x+3 replace y with -1
\n" ); document.write( "-1=x+3 minus three on both sides
\n" ); document.write( "-4=x there, so for the range value -1, the domain is -4.
\r
\n" ); document.write( "\n" ); document.write( "1:
\n" ); document.write( "1=x+3 minus three
\n" ); document.write( "-2=x .: [the sign for 'therefore'] for the range 1, the domain is -2.
\r
\n" ); document.write( "\n" ); document.write( "3:
\n" ); document.write( "3=x+3 minus three both sides
\n" ); document.write( "0=x so for range 3 domain is 0.
\r
\n" ); document.write( "\n" ); document.write( "5:
\n" ); document.write( "5=x+3 minus three both sides
\n" ); document.write( "2=x so for range 5 domain is 2
\r
\n" ); document.write( "\n" ); document.write( "We just put them in order. We were given range {-1,1,3,5} so our domain should be {X when y=-1, X when y=1, X when y=3, X when y=5} in that order. X when y=-1 was -4, X when y=1 was -2, X when y was 3 was 1, X when y was 5 was 2. Our answer is thus {-4,-2,1,2}.
