You can put this solution on YOUR website!
The stationary point(s) are where the derivative of the function = 0.
\n" ); document.write( "So:
\n" ); document.write( "y=3x^2–6x
\n" ); document.write( "First Derivative:
\n" ); document.write( "dy/dx=6x-6
\n" ); document.write( "Equate it to zero:
\n" ); document.write( "6x-6=0
\n" ); document.write( "Solve for x:
\n" ); document.write( "6x=6
\n" ); document.write( "x=1
\n" ); document.write( "Plug this value of x back into the original equation to get the Y-coordinate:
\n" ); document.write( "y=3x^2–6x
\n" ); document.write( "y=3(1)–6(1)
\n" ); document.write( "y=-3
\n" ); document.write( "So your answer is:
\n" ); document.write( "(1,-3)
\n" ); document.write( "--------------------------
\n" ); document.write( "To find out if it is a maximum or a minimum, you need to take the second derivative and determine it's sign. If second derivative is < 0, it is a max. If > 0 it is a min. I will leave that part to you.
