Determine the domain and range. Identify the period and amplitude. Graph the equation.
\n" ); document.write( "y=4cos(x)
\n" ); document.write( "---------
\n" ); document.write( "Domain: all real numbers
\n" ); document.write( "Range: -4<= y <= 4
\n" ); document.write( "Period = 2(pi)/4 = (1/2)pi
\n" ); document.write( "Amplitude: 4
