You can put this solution on YOUR website!
y=3+7x^2 ... this will be a function if there is a definite value of y existing for every value of x under consideration .it is so in this case and hence it is a function.
\n" ); document.write( "2. Find g(w) and g(w+1) Problem: g(x)=3x-5
\n" ); document.write( " given g(x) , to find g(w) , we have to substitute w in place of x in the given function = 3w-5
\n" ); document.write( " similarly by substituting w+1 in place of x we get
\n" ); document.write( " g(w+1) = 3(w+1)-5 = 3w+3-5 = 3w-2 \n" ); document.write( "

\n" );
