The function f(x)=x^2-10x+21 has a maximum value or a minimum value and determine the value.
\n" ); document.write( "-----
\n" ); document.write( "Since the coefficient of x^2 is positive, f(x) has a minimum value.
\n" ); document.write( "-------------
\n" ); document.write( "Min occurs when x = -b/(2a) = 10/(2) = 5
\n" ); document.write( "----
\n" ); document.write( "Max value = f(5) = 25 - 50 + 21 = -4
\n" ); document.write( "-------------------
