You can put this solution on YOUR website!
a. There is nothing that x is not allowed to be in this function, so the domain is all real numbers.
\n" ); document.write( "b. g(x)=2x-1
\n" ); document.write( "g(-1)=2(-1)-1
\n" ); document.write( "g(-1)=-2-1
\n" ); document.write( "g(-1)=-3
\n" ); document.write( "g(2)=2(2)-1
\n" ); document.write( "g(2)=4-1
\n" ); document.write( "g(2)=3
\n" ); document.write( "c. When the horizontal value (x) is -1, the vertical value (g(x) or y) is -3.
\n" ); document.write( "When the horizontal value (x) is 2, the vertical value (g(x) or y) is 3.
