Question 1: the following equation defines a function of x.
\n" ); document.write( "F(x)=-2x+3. If (6,n) is an element of the function, what is the value of n?
\n" ); document.write( "Ans: -2*6+3 = -12+3 = -9
\n" ); document.write( "-------------------------------

\n" ); document.write( "A. {(-3,4),(1,-9),(1,4)}:: no
\n" ); document.write( "------
\n" ); document.write( "B. {(0,-5),(0,4),(0,5)}:: no
\n" ); document.write( "-----
\n" ); document.write( "C. {(1,-1),(2,-1),(3,-3)}:: yes
\n" ); document.write( "-----
\n" ); document.write( "D. {(0,1),(1,-1),(1,0)}:: no
\n" ); document.write( "===========================================
