Let f(x) = 2x^2 − 9x
\n" ); document.write( "Then f'(x) = 4x-9
\n" ); document.write( "And f\"(x) = 4
\n" ); document.write( "----------------------
\n" ); document.write( "Find all extreme values (if any) of f on the interval [0, 9]. Determine at which numbers in the interval these values occur. NOTE: If there is no maximum value (or minimum value), then enter DNE in the corresponding blanks.
\n" ); document.write( "----
\n" ); document.write( "Solve 4x-9 = 0
\n" ); document.write( "x = 9/4
\n" ); document.write( "Since f\"(9/4) = 4 > 0,
\n" ); document.write( "-------
\n" ); document.write( "Maximum Value: DNE
\n" ); document.write( "Minimum Value: f(9/4) occurs at x = 9/4
