Write the equation of the axis of symmetry, and find the coordinates of the vertex of the graph of each function. Idetify the vertex as a maximum or minimum. Then graph the function. The first ones are REALLY HARD. However, I'll give an easy one so I can see it all done so I can figure out the hard ones. The problem is :
\n" ); document.write( "y = 3x^2 - 6x + 4
\n" ); document.write( "----
\n" ); document.write( "Since 3 is positive the parabola opens up.
\n" ); document.write( "It therefore has a minimum point.
\n" ); document.write( "That point occurs when x = -b/2a = 6/(2*3) = 1
\n" ); document.write( "---
\n" ); document.write( "The corresponding y-value is f(1) = 3-6+4 = 1
\n" ); document.write( "-
\n" ); document.write( "So the vertex is (1,1)
\n" ); document.write( "----
\n" ); document.write( "The axis of symmetry is a vertical line thru the vertex.
\n" ); document.write( "Its equation is x = 1.
